Crafting the perfect essay takes time and dedication. There are so many elements you have to worry about, such as tone, purpose, and correct spelling and grammar. Writing a strong topic sentences is another critical part in writing a cohesive essay. 

Without a strong topic sentence, you risk losing your reader and perhaps part of your grade. If it’s a college admissions essay, then you need it to be as strong as possible to back up your application. Learn about what steps you should take to write a strong topic sentence.

What Is a Topic Sentence? 

People often confuse a topic sentence with a thesis statement. A thesis statement is typically at the end of your opening paragraph, that dictates the main argument you’ll be making in your essay. 

Throughout your essay, you’ll have multiple topic sentences, as each paragraph should start off with one. This beginning sentence is used to direct the topic of the paragraph and outline the flow of the following sentences. It’s used to help guide your reader and to continue to keep them hooked on your overall essay. Without topic sentences, your essay will be unorganized, lack transitions, and sound very choppy. To write a good topic sentence, there are several steps to take.

Writing a Good Topic Sentence: 5 Steps

Step 1: decide what you’re going to write about..

When you see the essay prompt, you’ll have some time to think through what you want to say and why. You have to decide if it’s a persuasive essay, informative, narrative, or descriptive. Determine your purpose for writing the essay after reading through the prompt. Whether it’s an assignment for school or if it’s to get into college, you need to make sure you have that purpose clearly outlined. 

Step 2: Create a thesis statement.

One of the first things you need to do is create a thesis statement. This is typically a sentence with three points that you’ll back up throughout your essay. 

For example: The Office became a cultural phenomenon because it spurred the careers of many of today’s successful movie stars, it talked about situations that most American workers can relate to, and even 15 years later, offers funny, relevant content that helps to break down prejudices. 

You then use that thesis statement to create an essay around the points you want to make. 

Step 3: Make your essay outline.

Once you have the points you want to make within your thesis statement hammered out, make an outline for your essay. This is where you’ll start to create your topic sentence for each paragraph. You want to clearly state the main idea of that paragraph in the very first sentence. From there, you back up that main idea with facts and reputable sources. Make sure your topic sentence is clear, but does not just announce your topic. 

For example, do not write something like: “In this paragraph, I will discuss why it’s bad that poachers are killing giraffes.”

Instead, write something that clearly states your idea with a reasonable opinion and that gives direction to the paragraph: “Giraffes are a key part of the African ecosystem, so it’s important to enforce regulations against the poachers who are killing them for their body parts.” 

You’d then follow that up with reasons why giraffes are a key part of the African ecosystem and how poachers are destroying their population.

Step 4: Begin writing your essay.

Once you have your thesis statement and you’ve created an outline with supporting paragraphs and their topic sentences, you can begin writing your essay. It’s important to make that outline before just jumping in–a disorganized essay can spell disaster for you as you continue to write, and could result in a poor grade. Many times, teachers will even require you to turn in your outline as part of your overall essay grade. 

Step 5: Proofread and check your resources.

After you’ve written the essay, go back through it with a fine tooth comb. Read through each topic sentence and the paragraphs that follow to ensure that you’ve written clear, solid topic sentences throughout and that the paragraphs with them make sense. During the proofreading phase, you also need to recheck the sources you’re using. Make sure each source is reputable. In other words, do not use sites like Wikipedia where anyone can go in and edit an article to add misinformation. Use sites that:

• Are actual reputable news sources, such as the New York Times , CNN, CBS News
• Have domain names that end in .edu or .gov
• Come from an encyclopedia, such as Encyclopedia Britannica

Using sites that are not reputable could jeopardize the validity of your argument.

Now that you know the steps to set yourself up for success when writing a topic sentence, there are certain elements that go into a quality first sentence. Always make sure that your topic sentence is the first sentence of a paragraph. You don’t want to make your reader hunt for the point you’re trying to make. Check out some key elements of a good topic sentence:

Make sure your topic sentence isn’t too vague.

You need a topic sentence that has some specifics to it. It also needs to hook in your reader in some way with an opinion. A vague sentence makes it harder to write a paragraph that can clearly backs up your thoughts. For example:

DON’T: “In Pride and Prejudice, Mr. Bingley seems like a nice guy.”

DO: “When Mr. Bingley is first introduced, he comes across as a kind person because he speaks to everyone and doesn’t immediately pass judgment.”

Choose a reasonable opinion.

Your topic sentence should clearly outline whatever point you’re trying to make in the paragraph, but you want to pick a reasonable opinion that you can easily reinforce with facts and statistics. Here’s an example of what you should and should not do:

DON’T: “It’s obvious that Mr. Bingley was a total loser with no backbone.”

DO: “Mr. Bingley could have shown more confidence in his choices and stood up to Mr. Darcy when he found himself in love with Jane Bennet.”

You can then back that up with facts, saying that he was a wealthy Englishman and thus one of the key players in society at the time, which should have given him more confidence. If he’d been more confident, perhaps he would not have left and devastated Jane.

Use your topic sentence as a transition.

Along with telling the reader the point of your next paragraph, your topic sentence should also serve as a transition from the previous paragraph. Without a transition, the essay can feel like it’s choppy and disjointed. For example:

DON’T: “Mr. Bingley is a good man and here’s why.”

DO: “Although Mr. Bingley did break Jane’s heart by leaving, he ended up redeeming himself by returning to Netherfield Hall.”

Keep your topic sentence short.

A long, drawn-out topic sentence can risk losing your reader. Many times, it’s hard to determine the point of a sentence when it goes on for too long. You want a clear, concise sentence that draws in the reader but also leaves some room for you to expand on it in the following paragraph.

DON’T: “Throughout the novel of Pride and Prejudice, Mr. Bingley was often quite different from Mr. Darcy as he would treat all people in a friendly manner, considering them all his friends and acquaintances, even agreeing to throw a ball after Elizabeth’s sisters rudely demanded he do so and was gracious to Mr. and Mrs. Bennet as well despite their manners.”

DO: “Overall, Mr. Bingley served as a foil to Mr. Darcy throughout the story by treating everyone around him equally with dignity and grace.”

Writing an essay can be overwhelming at times, but so long as you avoid some of these common pitfalls, it can be easier to get it done on time. 

Don’t wait until the last minute.

If your teacher assigns you an essay or tells you that you have an essay test coming up, don’t wait until the day before to do anything about it. You have to plan or study and you need to give yourself time to do that. If you know it takes you a while to write something, then start planning it as soon as you get the assignment.

Don’t forget to write an outline.

Along with planning, make sure you have that outline written up and planned out well. It will serve as your guideline for writing the essay. Without it, you’ll face the risk of a disorganized essay that does not clearly illustrate your point.

Ask for help if you need it.

This may be the most important pitfall to avoid. If you get in over your head while writing, don’t be afraid to ask for help. Ask a friend to review the essay or ask your teacher for guidance.

How to Write a Topic Sentence (30+ Tips & Examples)

Writing the perfect topic sentence took me years to master.

After endless drafts, feedback sessions, and seeing what resonates with readers, I’ve distilled the ultimate guide to craft attention-grabbing, informative, and concise topic sentences.

Let’s dive into the essential tips for how to write a topic sentence.

What Is a Topic Sentence and Why Is It Important?

Table of Contents

A topic sentence introduces the main idea, usually appearing at the start of a paragraph.

It sets the tone for the entire paragraph by giving a glimpse of what’s coming. Think of it as a headline for each paragraph that keeps your writing clear and focused.

A strong topic sentence is important because:

• Grabs Attention: Captures the reader’s interest, encouraging them to keep reading.
• Guides Structure: Helps organize thoughts in a logical way.
• Provides Focus: Prevents rambling by clarifying the main point.

Types of Topic Sentences

Different types of topic sentences can fit various writing styles and purposes.

Understanding these types will help you select the best approach for your specific content.

• Declarative Statements: These are straightforward sentences that make a clear assertion. They introduce the main idea without any fluff or ambiguity. Example: “Water conservation is critical in regions prone to drought.”
• Interrogative Sentences: These topic sentences pose a question, encouraging readers to think critically and seek answers within the paragraph. Example: “How can sustainable practices help reduce waste in the fashion industry?”
• Complex Sentences: By combining independent and dependent clauses, these topic sentences present a nuanced main idea that prepares readers for a more detailed discussion. Example: “Although renewable energy sources are gaining popularity, fossil fuels still dominate the global energy sector.”
• Bridge Sentences: These link the preceding paragraph to the next, providing continuity and coherence in the overall structure. Example: “While electric vehicles offer a greener alternative to traditional cars, the infrastructure for widespread adoption remains lacking.”
• Contrasting Statements: These topic sentences highlight opposing viewpoints or circumstances, building intrigue and depth into the following paragraph. Example: “Despite the technological advancements in healthcare, access remains limited for underserved communities.”

My 30 Best Tips for Writing a Topic Sentence

Now let’s get into the main section of this guide — where you will learn all the best tips for writing a compelling topic sentence on any subject.

Tip #1: State the Main Idea Clearly

Make sure your topic sentence introduces the primary idea succinctly.

Avoid vague language or cluttered wording. Your reader should immediately understand the topic.

• Clear: “Recycling programs reduce landfill waste by promoting reusable packaging.”
• Unclear: “Programs for recycling can be a good thing because it’s important.”

Tip #2: Keep It Simple and Direct

A topic sentence should be straightforward. Avoid complex structures and over-complicated phrasing.

Shorter sentences work best.

• Simple: “Exercise improves mental health through endorphin production.”
• Complicated: “One can expect to experience benefits in their mental state with exercise due to the generation of endorphins.”

Tip #3: Link to the Previous Paragraph

Create a smooth flow by connecting ideas to the paragraph before.

Transition words like “similarly,” “however,” or “in contrast” help show relationships.

• Linked: “Similarly, the agricultural industry is also impacted by climate change.”
• Disjointed: “Farmers are struggling with erratic weather patterns.”

Tip #4: Avoid Announcing Your Intentions

Steer clear of sentences like “In this paragraph, I will discuss…” They sound amateurish and reduce reader engagement.

• Natural: “Effective communication skills are crucial for career advancement.”
• Announcing: “This paragraph will explain why communication skills are important.”

Tip #5: Vary Sentence Structure

Using the same structure repeatedly can bore readers.

Mix up your approach by experimenting with different forms like questions, facts, and lists.

• Varied: “How does cultural background influence consumer behavior?”
• Repetitive: “Consumer behavior is influenced by cultural background.”

Tip #6: Be Specific, Not General

A vague topic sentence leaves the reader confused. Instead, provide specific information to establish clarity and interest.

• Specific: “Remote work improves productivity by reducing commute times.”
• General: “Remote work is beneficial for many reasons.”

Tip #7: Reflect Your Argument’s Tone

Match your topic sentence with the tone of your argument. For serious discussions, avoid informal language.

• Formal: “The socioeconomic impact of urbanization requires comprehensive policy solutions.”
• Informal: “The effects of city living need some fixing.”

Tip #8: Include a Controlling Idea

The controlling idea limits the scope of the paragraph, ensuring the reader knows what to expect next.

• With Control: “Social media marketing increases brand visibility through targeted campaigns.”
• Without Control: “Social media is important.”

Tip #9: Use Active Voice

Active voice is more engaging and dynamic. It also provides clarity.

• Active: “New policies will reshape healthcare accessibility.”
• Passive: “Healthcare accessibility will be reshaped by new policies.”

Tip #10: Make It Unique

Avoid using overused phrases or predictable statements. Offer a fresh perspective to captivate your reader.

• Unique: “Biodegradable packaging is transforming the fast-food industry.”
• Cliché: “The fast-food industry is changing with new trends.”

Tip #11: Create Curiosity

Tease your reader by leaving questions unanswered. Encourage them to keep reading for more.

• Curious: “What are the unexpected benefits of rising inflation rates?”
• Blunt: “Rising inflation rates have some positive effects.”

Tip #12: Support Your Thesis

Your topic sentence should align with your overall thesis. It will give your argument more coherence.

• Aligned: “Reducing plastic waste aligns with our sustainability goals.”
• Unaligned: “Plastic recycling is controversial.”

Tip #13: Focus on One Point

Don’t overwhelm readers with multiple ideas in one topic sentence. Stick to one clear concept.

• One Point: “Artificial intelligence streamlines data analysis.”
• Too Broad: “Artificial intelligence changes marketing, finance, and data analysis.”

Tip #14: Use Key Terms From the Prompt (if applicable)

If you are responding to an assignment or specific topic prompt, make sure your topic sentence directly incorporates relevant keywords.

• Key Terms Included: “Global warming solutions must involve international cooperation.”
• Lacks Terms: “Solutions for the environment require cooperation.”

Tip #15: Offer Context

Provide some context in the topic sentence to frame the discussion, giving the reader essential background information.

With Context: “As urbanization accelerates, city infrastructure struggles to keep up.” Without Context: “City infrastructure is lagging.”

Tip #16: Incorporate Comparisons

Comparisons can clarify complex concepts and give readers a familiar reference.

• Comparison: “Just as the printing press revolutionized communication, the internet has transformed modern commerce.”
• No Comparison: “The internet has transformed modern commerce.”

Tip #17: Present Solutions

Offering a solution at the start engages readers who are seeking actionable advice.

• Solution: “Installing solar panels reduces energy bills while cutting carbon emissions.”
• Problem-Only: “High energy bills are a widespread issue.”

Tip #18: Address Common Misconceptions

Challenge preconceived notions to spark curiosity and highlight the importance of your argument.

• Challenging: “Despite common belief, vitamin supplements aren’t always beneficial.”
• Reinforcing: “Vitamin supplements have benefits.”

Tip #19: Use Emotional Appeals

Appeal to the reader’s emotions to deepen their connection to your writing.

• Emotional: “Volunteering at shelters uplifts communities and transforms lives.”
• Neutral: “Volunteering at shelters is helpful.”

Tip #20: Avoid Redundancy

Ensure your topic sentence adds new value. Avoid repeating points covered elsewhere.

• New Value: “Stronger copyright laws are crucial for protecting intellectual property.”
• Redundant: “Intellectual property needs stronger protection.”

Tip #21: Ask a Thought-Provoking Question

Pose a question that makes the reader stop and think. This engages them immediately.

• Provocative: “How will automation reshape the global workforce?”
• Plain: “Automation is changing the global workforce.”

Tip #22: Include an Action Verb

Action verbs add momentum and urgency to your topic sentence. They make your point more dynamic.

• Active Verb: “Investing in renewable energy fosters long-term economic growth.”
• Lacks Action: “Renewable energy investments are beneficial.”

Tip #23: Paint a Picture

Use descriptive language to help readers visualize your point.

• Descriptive: “Increased droughts have turned fertile farmlands into arid deserts.”
• Bland: “Droughts are affecting farmlands.”

Tip #24: Use Parallel Structure

Parallel structure involves repeating similar grammatical forms.

It makes your writing rhythmic and easy to follow.

• Parallel: “Tackling pollution requires reducing emissions, cleaning waterways, and limiting waste.”
• Non-Parallel: “Tackling pollution requires emission reductions, waterways cleaning, and limiting waste.”

Tip #25: Emphasize Urgency

Highlight the time-sensitive nature of your argument to create urgency.

• Urgent: “Immediate action is needed to prevent further deforestation.”
• Calm: “Deforestation is a concern.”

Tip #26: Highlight Contrasts

Contrasting different ideas helps to emphasize your point and draw clear distinctions.

• Contrast: “While technology creates new jobs, it also disrupts traditional industries.”
• No Contrast: “Technology affects the job market.”

Tip #27: Lead with a Statistic

Start with a compelling number to catch the reader’s attention and back up your argument.

• Statistic: “80% of small businesses struggle to comply with data privacy regulations.”
• General Statement: “Small businesses struggle with data privacy.”

Tip #28: Build on Existing Knowledge

Assume the reader has some background knowledge and expand on it.

• Builds On Knowledge: “With the rise of remote work, companies are rethinking their office spaces.”
• Basic Information: “Remote work is changing office spaces.”

Tip #29: Start with an Anecdote

A brief anecdote adds a human touch, creating an immediate connection with the reader.

• Anecdotal: “After years of burnout, Sarah switched to a part-time schedule to improve her work-life balance.”
• Abstract: “Work-life balance is important.”

Tip #30: Use an Engaging Metaphor

A metaphor can illuminate your argument in an unexpected way.

• Metaphor: “Effective teamwork is the glue that holds successful organizations together.”
• Literal: “Effective teamwork is important for organizations.”

What is a Topic Sentence? (Definition, Examples, How to Use)

What is a topic sentence ? A topic sentence , the first sentence of a paragraph, presents the main concept discussed in the paragraph. It must contain sufficient information to support numerous examples and subtopics without being too broad to obscure the essay’s intended purpose. The remaining sentences in the paragraph will act as supporting statements, providing evidence and examples for the main idea.

Importance of topic sentences

In essays or articles , where subjects can shift from one paragraph to another, a topic phrase is particularly crucial. The topic sentences, superficially, may seem to serve the purpose of only acting like the initial or introductory sentence of a paragraph. But it has numerous other purposes that make it an important part of essays.

• Topic sentences link paragraphs together to improve the sentence flow and make reading easier. When topic sentences are not used, switching between paragraphs can feel abrupt and jarring to the reader. Authors can maintain the rhythm of their writing using topic sentences and facilitate smooth transitions.
• Topic sentences show the reader a sample of what to expect from the paragraph. The readers can determine from the topic sentence whether the paragraph will comprise a narrative, a list, anecdotal evidence, statistical data, persuasive opinions, or some other form of evidence.
• If two conflicting viewpoints are presented in a single paragraph, authors can use more than one topic sentence to inform the readers about the changes in the main concept. For example, paragraphs that “compare and contrast” require more than one topic sentence. In these kinds of paragraphs, authors can start with a topic sentence introducing the first idea and follow it up with proof or evidence supporting the idea. Then they can introduce the second topic sentence conveying the opposing viewpoint, followed by proof or evidence supporting it.

Different types of topic sentences

The different types of topic sentences include:

Simple statement

This topic sentence is used by authors to make a general observation or statement and then elaborate on it in the body of the paragraph.

New studies are emerging indicating the link between climate change and the emergence of numerous new virus strains.

Interrogative or question

This is used by writers in less formal settings. Authors can start a paragraph using implicit or explicit questions related to the topic of discussion to engage the readers.

How many nations are ready to adapt to rising sea levels?

Complex topic sentences are used when the author is discussing a complicated concept that encompasses multiple ideas. Such topic sentences cover more than a single core idea.

Although many people believe that a mother bird will reject its chick if it is touched by humans, the truth is that birds do not abandon their babies after humans touch them.

Authors can use their topic sentences to make explicit demands or pleas to their readers. This will be helpful in breaking the monotony of the essay.

Let’s look at the data from the latest research.

Purely transitional

Though topic sentences are generally responsible for facilitating a smooth transition between paragraphs, occasionally they are purely transitional. These function best when the main topic shifts abruptly by highlighting the switch.

But not everybody agrees.

Pivot sentences are not found at the beginning of a paragraph but rather in the middle, indicating a change in the topic. Conjunctive adverbs like however, furthermore, and meanwhile are frequently used with them.

However, the undisputed king of tennis, Roger Federer, was dethroned in 2008 at Wimbledon.

How to create good topic sentences

A good topic sentence can be created using some simple steps:

1. Determine the key point of your essay

Writers should first form an understanding of the topic of the essay and then create topic sentences to attract the attention of readers. Constructing a good thesis statement can assist the writer in forming better topic sentences.

2. Have an outline for the essay

The author should form a plan or roadmap beforehand on the topics they want to discuss in a paragraph and the evidence they want to use as supporting statements.

3. Be coherent and clear

Writers should make their topic sentences clear and comprehensible so that the reader can form a clear understanding of what to expect in the paragraph.

4. Share opinions

It is advisable to share the opinion or viewpoint of the author in the topic sentence to attract the attention of the reader. Authors should also refrain from writing obvious facts in the topic sentences.

5. Use specific wordings

The topic sentences ought to be precise enough so that the authors can use a few sentences in the paragraph to support them.

6. Transitions should be added between paragraphs

To give the essay or paper a throughline, authors can create topic sentences that refer to the prior paragraph. A topic sentence can make a reference to the preceding paragraph while introducing the next part by using transitional words.

7. Use new, relevant information

Instead of using an obvious fact that everybody knows as the topic sentence, authors can give new information. It is also important to present them in an interesting way.

8. Create a compound or complex topic statement

Compound or complex topic statements feel advanced and stronger. Authors can create such topic statements to add a high level of sophistication to their text.

Many beginner writers and students confuse thesis statements with topic sentences. In essence, thesis statements establish the major idea discussed in the entire essay or paper, as opposed to topic sentences, which introduce the central concept of a paragraph.

Both of these sentences are responsible for giving the readers a sample of what to expect, but in entirely different capacities. Suppose a person is writing a thesis about the different compounds present in coffee and the health benefits it offers.

The thesis statement will be a generalized statement indicating that there are numerous compounds in coffee that benefit the health of humans. But the topic sentence of each paragraph will introduce any single health benefit or compound present in the coffee.

Topic sentences are typically found at the beginning of a paragraph. But this does not mean that they cannot be placed elsewhere in the paragraph. In some cases, when the details discussed can be summarized into a general statement, topic sentences can be included at the end.

Similarly, in some paragraphs where multiple concepts are discussed, topic sentences may be used in the middle of the paragraph. The placement depends on the number of topics being discussed and the way they are discussed.

Paragraphs: Topic Sentences

Topic sentences video playlist.

Note that these videos were created while APA 6 was the style guide edition in use. There may be some examples of writing that have not been updated to APA 7 guidelines.

• Academic Paragraphs: Introduction to Paragraphs and the MEAL Plan (video transcript)
• Academic Paragraphs: Examples of the MEAL Plan (video transcript)

The best way to understand the role of the topic sentence in paragraph development is to imagine that any given paragraph is a miniature essay that has its own thesis, support, and conclusion. The parts of a paragraph easily correspond to the parts of an essay:

Just as an effective essay starts off with an introduction that presents the paper's thesis statement and indicates the specific claim or argument that the essay will develop, each paragraph should begin with a topic sentence that indicates the focus of that paragraph, alerting the reader to the particular subtopic that the paragraph will provide evidence to support.

A strong topic sentence should be placed at or near the beginning of a paragraph. In addition, this sentence should focus on a specific issue, avoid the use of direct quotations, and leave room for support and analysis within the body of the paragraph. Read on to learn more about creating an effective topic sentence.

The topic sentence does not have to be the first sentence in the paragraph; however, it should come early in the paragraph in order to orient the reader to the paragraph's focus right away. Occasionally a writer may place a transition sentence before the topic sentence, to create continuity between topics.

Topic Sentence to begin paragraph:

In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

Transition Sentence + Topic Sentence to begin paragraph:

However, Morrison does not only use the emotional and spiritual bonds between her female characters to initiate their coming-of-age. In addition, the author uses the physical bonds of female friendship to propel her adolescent protagonists into self-awareness.

Specificity

Your topic sentence should be more narrowly focused than your thesis sentence, and you will want to make sure the claim you are making can be supported, argued, and analyzed within the body of your paragraph.

Example: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

In this topic sentence, the essayist is arguing that physical bonds of friendship, specifically, make the female characters more self-aware. Because this idea can be refuted or supported by readers (based on how successfully the essayist persuades his or her readers with examples and analysis from the novel), and because the claim is narrow enough to address within a single paragraph, the above sentence is a successful topic sentence.

Direct Quotations (Are Best Avoided)

Although it might be tempting to begin a paragraph with a compelling quotation, as a general rule, topic sentences should state the main idea of the paragraph in your own words. Direct quotations have a place later in the paragraph, where they may be incorporated to support the topic sentence.

Needs Improvement: As Morrison (1982) conveyed, the girls' "friendship let them use each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

Better: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness. Pointing to the connection of eyes meeting and bodies growing together, Morrison makes coming-of-age an interactive physical process between the adolescent protagonists. Specifically, Morrison describes how Sula and Nel have used "each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

In this second paragraph, the topic sentence appears first, immediately orienting readers to the main focus (or topic) of the paragraph. The quotation is used later in the paragraph as a form of evidence or support for the topic sentence.

If you are finding it challenging to create effective topic sentences, you might consider outlining before beginning to write a paper. The points and subpoints of an outline can then become the topic sentences for the paper's paragraphs.

Additionally, because the topic sentence functions similarly at the paragraph level to the thesis at the essay level, you may also find it helpful to check out our thesis statement construction information. Our resource on paragraphs has helpful information about the scope of a paragraph, as well.

The structure of academic writing requires several standards to be followed to ensure the coherence of your essay. One of the techniques you should use in your writing is essay topic sentences. However, why is it necessary, and how to write a topic sentence? We will answer this and many further questions in this article. Keep reading if you want to know:

• The essence of the topic sentence and its use;
• The crucial aspects of composing a topic sentence;
• Types of topic sentences and their implementation in the text;
• How to write your topic sentence and see the examples of it.

A strong topic sentence is a guarantee to be heard by the readers! Let’s start by looking at the meaning of this term and the main purpose of topic sentence.

What Is a Topic Sentence

A topic sentence is a generalized main idea of a paragraph summarized in one phrase. This statement provides a smooth transition from one central point to the next. But do not confuse it with the thesis statement. So, let’s review the topic sentence vs thesis statement and see if there is any difference.

A thesis statement sums up the idea of your essay or thesis, but it is usually found in the introduction, presenting the main point of the whole piece. Our service is ready to help you with writing a thesis statement correctly to ensure the highest results. An effective topic sentence includes two parts: the topic and the controlling idea. Use a topic sentence to organize your formal writing. Thus, you will delimit the main ideas within the boundaries of your essay paragraphs and ensure your text is coherent. This technique also aims to interest the reader by revealing the concept of your written work.

Characteristics of an Effective Topic Sentence

Using a topic sentence is an efficient strategy that will inform a reader about the topic of its paragraph briefly. To achieve this result of idea explanation and its evolution through the following parts of the text, learn the main characteristics of effective topic sentences. Below, we listed particular features that create a perfect topic sentence formula.

A good topic sentence requires clarity and unambiguity. The reader must understand exactly what work he is about to read. Therefore, your task is to introduce the main idea of each paragraph clearly.

Always remember about the idea of your paper, and don’t add anything extraordinary. You should only include information in your topic sentences that will be presented in the supporting sentences of the body part of an essay . Thus, your text will be easy and exciting to read, regardless of the topic.

• Completeness

You are faced with the difficult task of condensing a complete main idea into just one topic sentence. It must be comprehensive, express a complete thought, contain the controlling idea, and convey the topic you presented in a particular paragraph.

The topic sentences should motivate further reading. Therefore, you should present the information in a captivating way, ensuring the reader’s interest.

Types of Topic Sentences

There are three main types of topic sentences that cover a wide range of functions. Each type is suitable for a different purpose, but they all aim to include the key information in the current paragraph and emphasize the reader’s attention to it.

Interrogative

The topic sentence is presented as a question, and the following paragraph provides the answer. Such a topic sentence will effectively attract attention, increasing interest in reading. However, be careful to give an unambiguous answer to the question posed in your topic sentence.

Topic: Fast fashion

Topic sentence: What changes are required in the organization of the fashion industry to overcome total environmental pollution?

Reinforcement

Topic sentences and supporting details can serve as a reinforcement, supporting the central idea expressed in the essay’s thesis statement. This keeps the story flowing, showing that you’re not jumping between ideas inconstantly.

Thesis statement: AI development will provide the labor market with dozens of new positions.

Topic sentence: A lot of new job opportunities will be discovered with the development of AI.

Transitional

The topic sentences can also play the role of a link, logically and smoothly connecting several paragraphs into one whole. In this way, a clear structure of academic writing is maintained, and the author can relate one central point to another.

Last sentence of the previous paragraph: The issue of the need for school uniforms has been actively discussed for many years.

Topic sentence: School uniform is necessary for the development of discipline in children.

How to Write a Good Topic Sentence

First, remember that the focus sentence is the most important sentence in a paragraph. It should not only state the paragraph’s main idea, but it should be intriguingly interesting, concise, and include a controlling idea. Experts of our writing service have prepared for you some tips on how to make a topic sentence. It’s important to consider many different factors before writing a topic sentence for an essay. Keep reading to see the most essential ones.

Understanding the Paragraph’s Main Idea

The key to writing the topic sentence is to determine the main point of the paragraph. Think about the purpose for which you wrote this fragment. What would you like the reader to remember most? In other words, if you extract all the topic sentences from your essay and compose a text from them, you will get a complete digest of all the main ideas of the thesis.

Keeping it Concise

Sometimes, it can be difficult to fit everything you want to convey to the reader into one concluding sentence. After all, everything you wrote is valuable information worthy of attention. Still, be brief when writing your topic sentence to entice the audience to continue reading the rest of the paragraph.

Positioning the Topic Sentence

The topic sentence can be written in any part of the paragraph. Most commonly, placing it in the beginning, thus you ensure a smooth transition from the previous paragraph and give readers a hint about what the upcoming piece will be about. If it’s in the middle of the text, it can describe the main idea after having revealed some crucial background details of the main idea. When you write the topic sentence at the end of the paragraph, it concludes and highlights the essential concepts of the piece.

Make it Interesting but not Over-complicating

To start with, brainstorm to point out the most creative and interesting idea for your topic sentences. For example, if you use statistics in later paragraphs, include them in the hook sentence as well, this will intrigue readers. At the same time, do not forget that due to the topic sentence structure, the size of the topic sentence is very limited, so do not try to overcomplicate it.

Better to Use Active Voice

From a grammatical and lexical point of view, it is believed that the passive voice complicates the construction of sentences. You may consider the previous sentence as an example of a topic sentence that is difficult for a reader. Your topic sentences should be brief and comprehensive yet simple to understand. Prefer active voice to make the body paragraph easier to read.

Enhance with Evidence

First of all, any essay, likewise scientific work, requires accuracy. That is why using verified statistical data and citing reliable sources makes your topic sentence and controlling idea credible and respected. Pay attention to the plausibility of data when you write academic essay papers to avoid misleading information. Topic sentences for essays should also contain precise facts, which you subsequently describe in the new paragraph.

Bind the Paragraph Together by Repeating Words or Phrases

In poetry, there is a technique called anaphora, when each line or sentence of a verse begins the same. This is often used to influence the reader’s emotions, strengthening his awareness of a certain concept of the subject. So, to reinforce your main idea and relate your paragraphs, you can also use this device in your essay writing.

Use Transition Words

Of course, without connecting words, argumentative essays will turn into a collection of words and incoherent sentences. Build a clear essay structure by combining topic sentences with the rest of the paragraph with linking words. Therefore, to make your narrative coherent and logical, you should soften the transitions. Introduce these words at the beginning: first of all, to start with, therefore, based on this, moreover, and many others to enrich your writing.

Examples of Topic Sentences

Modern technologies have helped to significantly simplify working conditions for people. For centuries, people have had to work hard to provide basic means of living. In the absence of mechanization, unfathomable amounts of effort were required to complete basic tasks. For this reason, people worked day and night for six days a week and, in some cases, without days off at all. However, our generation was much luckier. The development of artificial intelligence and the automation of most production processes at this point allow people to work more efficiently while spending less time and effort.

What we know about recycling is a drop, what we don’t know is the ocean. In recent years, there have been many environmental campaigns to explain the importance of recycling. Most developed countries invest a large share of their budget in developing environmental solutions for the most optimal recycling of waste. However, at the same time, ordinary users still know very little about the rules for sorting waste. In reality, only a very small percentage of plastic can be recycled. Few people know that only the cap of a plastic bottle is recycled.

Society is moving online, and the changes it brings to the future are difficult to ignore. Of course, we don’t know exactly what the future of our society will be, but now we can trace some trends that will lead to steady changes. The children from the youngest age know how to use gadgets and independently find information on the Internet. Friendship, relationships, study, work, and all this already exist in the electronic dimension. Sociologists are interested in the question of what the society of the future will look like and whether there will be a place for offline communication in it.

The eternal question of style: to follow or not to follow the fashion trends. There probably is no single correct answer to this question. Social media influencers are actively sharing the hottest trends in the fashion world. The main fashionistas immediately run to the store to buy the latest new items. However, one thing is obvious – trends are certainly not for everyone. Starting from different body types to color types. We are all different, and this is our uniqueness. Trends certainly cannot look complimentary to everyone.

Our inner confidence provides external attractiveness. I have seen more than once that confident people often receive more positive attention. This is due to certain biological factors since a person with leadership qualities can lead a community, and therefore, people are drawn to him/her. And yet the advantage is not only respect from others. People with high self-esteem are perceived as more physically attractive.

Topic Sentences as an Integral Part of Every Paragraph

Your creative ideas that bring scientific novelty are the key element of your academic essays. At the same time, an idea without form is just a set of concepts. Using topic sentences will help you navigate and organize your ideas in a logical flow. Furthermore, it not only provides direction and focus for a paragraph, ensuring coherence and unity, but it also guides the reader’s journey through a text.

Paragraphs & topic sentences.

A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.

Paragraphs can contain many different kinds of information. A paragraph could contain a series of brief examples or a single long illustration of a general point. It might describe a place, character, or process; narrate a series of events; compare or contrast two or more things; classify items into categories; or describe causes and effects. Regardless of the kind of information they contain, all paragraphs share certain characteristics. One of the most important of these is a topic sentence.

TOPIC SENTENCES

A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.

Although most paragraphs should have a topic sentence, there are a few situations when a paragraph might not need a topic sentence. For example, you might be able to omit a topic sentence in a paragraph that narrates a series of events, if a paragraph continues developing an idea that you introduced (with a topic sentence) in the previous paragraph, or if all the sentences and details in a paragraph clearly refer—perhaps indirectly—to a main point. The vast majority of your paragraphs, however, should have a topic sentence.

PARAGRAPH STRUCTURE

Most paragraphs in an essay have a three-part structure—introduction, body, and conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating your meaning to your reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea.

The following paragraph illustrates this pattern of organization. In this paragraph the topic sentence and concluding sentence (CAPITALIZED) both help the reader keep the paragraph’s main point in mind.

SCIENTISTS HAVE LEARNED TO SUPPLEMENT THE SENSE OF SIGHT IN NUMEROUS WAYS. In front of the tiny pupil of the eye they put , on Mount Palomar, a great monocle 200 inches in diameter, and with it see 2000 times farther into the depths of space. Or they look through a small pair of lenses arranged as a microscope into a drop of water or blood, and magnify by as much as 2000 diameters the living creatures there, many of which are among man’s most dangerous enemies. Or , if we want to see distant happenings on earth, they use some of the previously wasted electromagnetic waves to carry television images which they re-create as light by whipping tiny crystals on a screen with electrons in a vacuum. Or they can bring happenings of long ago and far away as colored motion pictures, by arranging silver atoms and color-absorbing molecules to force light waves into the patterns of original reality. Or if we want to see into the center of a steel casting or the chest of an injured child, they send the information on a beam of penetrating short-wave X rays, and then convert it back into images we can see on a screen or photograph. THUS ALMOST EVERY TYPE OF ELECTROMAGNETIC RADIATION YET DISCOVERED HAS BEEN USED TO EXTEND OUR SENSE OF SIGHT IN SOME WAY. George Harrison, “Faith and the Scientist”

In a coherent paragraph, each sentence relates clearly to the topic sentence or controlling idea, but there is more to coherence than this. If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old information and new information to make the structure of ideas or arguments clear to the reader.

Along with the smooth flow of sentences, a paragraph’s coherence may also be related to its length. If you have written a very long paragraph, one that fills a double-spaced typed page, for example, you should check it carefully to see if it should start a new paragraph where the original paragraph wanders from its controlling idea. On the other hand, if a paragraph is very short (only one or two sentences, perhaps), you may need to develop its controlling idea more thoroughly, or combine it with another paragraph.

A number of other techniques that you can use to establish coherence in paragraphs are described below.

Repeat key words or phrases. Particularly in paragraphs in which you define or identify an important idea or theory, be consistent in how you refer to it. This consistency and repetition will bind the paragraph together and help your reader understand your definition or description.

Create parallel structures. Parallel structures are created by constructing two or more phrases or sentences that have the same grammatical structure and use the same parts of speech. By creating parallel structures you make your sentences clearer and easier to read. In addition, repeating a pattern in a series of consecutive sentences helps your reader see the connections between ideas. In the paragraph above about scientists and the sense of sight, several sentences in the body of the paragraph have been constructed in a parallel way. The parallel structures (which have been emphasized ) help the reader see that the paragraph is organized as a set of examples of a general statement.

Be consistent in point of view, verb tense, and number. Consistency in point of view, verb tense, and number is a subtle but important aspect of coherence. If you shift from the more personal "you" to the impersonal “one,” from past to present tense, or from “a man” to “they,” for example, you make your paragraph less coherent. Such inconsistencies can also confuse your reader and make your argument more difficult to follow.

Use transition words or phrases between sentences and between paragraphs. Transitional expressions emphasize the relationships between ideas, so they help readers follow your train of thought or see connections that they might otherwise miss or misunderstand. The following paragraph shows how carefully chosen transitions (CAPITALIZED) lead the reader smoothly from the introduction to the conclusion of the paragraph.

I don’t wish to deny that the flattened, minuscule head of the large-bodied "stegosaurus" houses little brain from our subjective, top-heavy perspective, BUT I do wish to assert that we should not expect more of the beast. FIRST OF ALL, large animals have relatively smaller brains than related, small animals. The correlation of brain size with body size among kindred animals (all reptiles, all mammals, FOR EXAMPLE) is remarkably regular. AS we move from small to large animals, from mice to elephants or small lizards to Komodo dragons, brain size increases, BUT not so fast as body size. IN OTHER WORDS, bodies grow faster than brains, AND large animals have low ratios of brain weight to body weight. IN FACT, brains grow only about two-thirds as fast as bodies. SINCE we have no reason to believe that large animals are consistently stupider than their smaller relatives, we must conclude that large animals require relatively less brain to do as well as smaller animals. IF we do not recognize this relationship, we are likely to underestimate the mental power of very large animals, dinosaurs in particular. Stephen Jay Gould, “Were Dinosaurs Dumb?”

Topic Sentence and Paragraph Organization

Paragraph organization refers to the way sentences are structured and ordered to create a unified and cohesive body of text.

The principal features to consider in paragraph organization are the topic sentence and controlling idea, supporting details, organizational patterns, and signal words. Together, these features develop a topic and connect ideas from one point to the next, logically and fluidly. This resource explains these features and provides numerous examples of paragraph organization.

The Topic Sentence and Controlling Idea

Similar to a thesis statement, which establishes the central focus or point of a whole piece of writing, a topic sentence works at the paragraph level to express the focus and general point of an individual paragraph. A topic sentence has two parts: 1) the topic that is being discussed throughout the paragraph and 2) a controlling idea that limits the focus on the topic to one point or idea. Each additional sentence in the paragraph then develops or expounds on that point with supporting details. The example topic sentence below is from a body paragraph in an informative essay.

Example Topic Sentence and Controlling Idea

The economy also plays a role in an increase in prescription pain reliever addiction.

The example topic sentence suggests the paragraph topic is “the economy,” and the controlling idea about the economy is how it “plays a role in an increase” in opioid addition. The signal word “also” connects this topic as an additional example or contributing factor to the opioid epidemic, the focus of the paper. The example below shows the topic sentence in the context of the complete paragraph.

The economy also plays a role in an increase in prescription pain reliever addiction. According to Jungeun Olivia Lee, a social work professor at University of Southern California, “The relationship between joblessness and substance abuse is strongest among people from low socioeconomic brackets, who might not be able to afford healthier ways to relieve their stress” (2017, as cited in Khazan, 2017, para. 8). Additionally, every point the unemployment rate rises, opioid-related death rates rise by almost 4 percent (Khazan, 2017). Unemployment makes it not only difficult for those suffering from pain to afford medication or healthy alternatives, but it can also contribute to depression and varying degrees of self-medication and addiction.

Supporting Details

In a paragraph, the topic and controlling idea are developed with supporting details. Listed here are some types of supporting details found in paragraphs along with an example of each in a sentence.

Facts: statistics or evidence from research that can be verified

• The office sold seven million dollars of real estate during the boom years.

Opinions: statements, quotes, or paraphrases from subject matter experts

• According to expert tea maker, Millie Stoff, there are three easy steps to making tea.

Definitions: explanations of what a term or concept means

• A crossover is a family vehicle with the features of a sedan, a mini-van, and an SUV.

Examples: parts, pieces, instances, traits, or specimens that illustrate the essence or character of a greater whole.

• Mario is a shy, introverted young man. For example, he has few friends and mostly keeps to himself.

Anecdotes: narrative accounts of one time or recurring events

• When I visited the Washington Monument, I enjoyed the 180-degree view the most.

Descriptions: a visual or sensory depiction of a person, place, event, activity, or idea

• Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees.

Example Paragraph and Analysis of the Supporting Details

Hiking can be exhilarating during snowy winter months. When my friend and I visited North Carolina last January, we hiked in the Blue Ridge Mountains near the highest peak, Mount Mitchell, which is6,684 feet above sea level. We first crossed a foot bridge over a rapidly moving, ice-cold river and then followed a wooded trail up to a waterfall. Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees. We saw deer and rabbits as we trekked up the path. I assure you that nothing feels better than inhaling crisp mountain air, but the neatest part of hiking in winter, besides the beauty of the mountain, is exhaling and seeing my breath turn to frost when it hits the cold air!

The topic sentence in the example paragraph indicates that the paragraph is on “hiking,” and the focus is that hiking is “exhilarating” during winter. The sentences in the paragraph support and develop this idea with an anecdote of the writer’s experience hiking up a mountain during winter. An anecdote is a narrative account that helps a reader understand an event or situation. Had the writer said hiking was “dangerous” instead of “exhilarating,” the anecdote in addition to the visual and sensory details, facts, and opinions about the experience would have been different. Additionally, while the sample paragraph is a personal account, writers in many professions use anecdotal evidence to report events from an objective point-of-view, where the writer is not a participant but rather a witness or observer.

Paragraph Organization

Along with having topic sentences and supporting details, paragraphs are also organized to achieve a certain purpose. However, just as a paragraph can contain different types of supporting details, a paragraph may also include more than one organizational pattern. Listed here are some common patterns for organizing a paragraph:

• Cause and Effect for showing how one thing leads to another
• Chronological Order for narrating events that occurred over time
• Classification for grouping things together according to their features
• Comparison and Contrast for showing how things are similar or different
• Definition and Example for defining a term or idea and then expanding it with examples
• Description for listing details
• Episode for presenting details or information about a specific event or anecdote
• General/Specific Order for presenting a general idea followed by specific examples
• Generalization/Principle for making a general statement or applying a broad principle to explain the supporting details
• Listing for presenting ideas from least to most important
• Order of Importance for building up to or leading away from the most important point.
• Problem and Solution for presenting an issue and a way to address it
• Process/Cause for explaining what or how something happens and then why
• Spatial Order for ordering details directionally

Signal Words

Signal words are signposts or clues to a paragraph’s organization. If the word “type” is used in a sentence, for example, it signals that the ideas involve types or classification, which is an organizational pattern. Signal words are context clues that hint at what the paragraph is about and how it is organized.

Listed here are signal words associated with different types of paragraph organization.

• Cause and Effect : because, consequently, for this reason, hence, and on account of
• Chronological Order : after, at last, at (time), as long as, at the same time, as soon as, before, during, eventually, finally, in (month or year), later, meanwhile, next, on (day or date), since, second, subsequently, then, until, and whenever
• Classification : categories, classes, classifications, elements, features, groups, kinds, methods, types, varieties, and ways
• Comparison and Contrast : another, both, however, likewise, one difference, on the other hand, on the contrary, similarity, similarly, unlike, and while
• Definition and Example : concept, defined as, described as, e.g., for example, for instance, i.e., illustrates, is, is called, is stated, known as, means, refers to, specifically, such as, term, and that is to say
• Description : above, across, along, appears to be, as in, behind, below, beside, between, down, in back of, in front of, looks like, near, onto, on top of, outside, over, such as, to the right/left, and under
• Episode : a few days/weeks later, around the same time, as a result of, as it is often called, because of, began when, consequently, for this reason, just, lasted for, led to, shortly thereafter, since then, subsequently, this led to, and when
• General/Specific Order : for example, for instance, indeed, in fact, in other words, like, namely, such as, and that is
• Generalization/Principle : additionally, always, because of, clearly, conclusively, first, for instance, for example, furthermore, generally, however, if…then, in fact, it could be argued that, moreover, most convincing, never, not only…but also, often, second, therefore, third, truly, and typically
• Listing : additionally, also, and, as well as, besides, furthermore, in addition, in fact, moreover, or, plus, and too
• Order of Importance : central, chief, ending with, finishing with, key, lastly, least, main, major, finally, primary, principal, and significant
• Problem and Solution : answer, challenge, difficulty, dilemma, enigma, indicate, improve, issue, need, plan, problem, propose, resolve, respond, solve, and suggest
• Process/Cause : accordingly, as a result of, because, begins with, consequently, effects of, finally, first, for this reason, how to, how, if…then, in order to, is caused by, leads/led to, may be due to, next, so that, steps involved, therefore, thus, and when…then
• Spatial Order : above, below, behind, beside, down, east, feels, highest, looks, lowest, next to, north, smells, sounds, south, tastes, under, and west

Sample Paragraphs and Analyses of the Organization

The sample paragraphs in this section illustrate topic sentences, supporting details, organizational patterns, and signal words in context. Read each paragraph to identify the type of paragraph organization on your own, and then proceed to the analysis to check your comprehension.

Sample Paragraph 1

• In 1995, Lawrence started his real estate business, and it has since become a huge success. When Lawrence Real Estate opened its door in Oviedo, Florida, it sold seven million dollars of real estate during the first few boom years. By 2000, Lawrence decided to open two branch offices: one in Tampa in 2003 and one in Miami in 2004. By 2007, the home office and both the branch offices had survived the economic slowdown, so Lawrence and his associates expanded their business to the Carolinas and opened a branch office in Charlotte in 2020. It can be safely said that Lawrence Real Estate has become a model for success despite economic struggles and real estate devaluation.

Analysis of Paragraph 1: According to the topic sentence, which contains two coordinating clauses and therefore two subjects and two topics, this paragraph is about Lawrence and his real estate business, and the controlling idea is that they have been successful.

To understand how the supporting details are organized to present information about this topic and idea, the reader can consider the supporting details. To do this, they look at the way the sentences begin and at any signal phrases that lead readers along a certain line of thinking. Here are some key signal words: “in 1995,” “By 2000,” “By 2007,” and “in 2020.” These dates make a pattern. They go back to 1995 and then in a chronological order, they move forward to when the success of the business happened.

This paragraph uses chronological order . The reader will notice too that the last sentence returns to the beginning idea of 15 years ago. In this sentence, a final comment about the time period overall is given with respect to the new information

Sample Paragraph 2

• Making a great cup of tea is easy if you follow these three steps. First, heat a cup of water to the boiling point. Then put the tea bag in the hot water, and let it steep for at least three minutes. Finally, add creamer and sugar to taste. There is nothing tastier than a strong cup of tea early in the morning.

According to the topic sentence, which is the first sentence of the paragraph, making a cup of tea is the topic, and the controlling idea is that it’s easy to do if you follow three steps. Signal words open the following sentences: “first,” “then,” and “finally.” These indicate a sequence of steps, not times or dates as in a narrative story, but steps that happen in a specific order as in the process of doing something or informing others how to do something.

This paragraph uses process order (or process/cause). In the last sentence of this paragraph, the process is completed with a return to the original topic—a cup of tea—and a new comment about it—that a strong cup is tasty in the morning, making those three steps not only easy but also worthwhile.

Sample Paragraph 3

• The Washington Monument is divided into three main areas. The lowest section of the building houses the entrance, a gift shop, and a restaurant. The middle section consists of elevators and stairways to the top. The top section of the monument includes an observation deck with a spectacular view of the Washington D.C. area. When I visited the Washington Monument, I toured every section but enjoyed the spectacular 180-degree view the most.

Based on the topic sentence at the beginning of the paragraph, the topic is the Washington Monument, and the controlling idea is that it is divided into three main areas. The paragraph presents information about the lowest section first, the middle section second, and the top section third. The last sentence makes a remark about the most enjoyable of all the sections. This is an example of spatial organization . The information is given in the order you might see it if you were there.

Sample Paragraph 4

• There are three types of family vehicles made in the United States. The first type is the minivan. All American car manufacturers make a version of the minivan. Some say that the comfort and amenities of the minivan compare to none. The second type of family vehicle is the SUV. Some SUVs offer four-wheel-drive to navigate tough terrains, and they also offer seating for a large crowd. A third type of family vehicles is called the crossover. These vehicles supposedly have the best features of the sedan, minivan, and SUV. They are easy to maneuver, look much like a regular sedan, and sit up to six people. All of these vehicles are family friendly; they offer safety, roomy comfort, and many extra features to accommodate the special needs of families.

This paragraph shows another way to organize the details of a topic. The topic sentence of this paragraph is structured differently than the previous ones. Typically, the topic of a sentence is also the grammatical subject, but the subject in this sentence is “there,” a pronoun, and the topic that tells what the paragraph is about, “family vehicles,” is in the predicate of the sentence. The controlling idea is that there are three types made in the U.S.

The paragraph is organized according to those three types: the first type, the second type, and the third type. To conclude, there is a comment about “all of these vehicles” or all of these types of vehicles. When information is organized by types or features, the information is classified. This type of organization is classification .

Sample Paragraph 5

• Although the twin brothers share many physical characteristics, they handle themselves differently in social situations. Mario is a shy introverted young man. He has few friends and mostly keeps to himself. On the other hand, Gino is outgoing and the life of the party. Unlike Mario, Gino has many friends and feels totally at ease among big crowds. The best way to tell these identical twins apart is to invite both to a party and observe how differently they interact with the other guests.

When the topic sentence is complex (having more than one clause) as in this paragraph, there may be two subjects and therefore two topics; however, here, the subject of the first clause is “the twin brothers” and the subject for the second clause is “they,” so both subjects refer to the same topic—the twin brothers. The controlling idea is that the twin brothers share many physical characteristics but handle themselves differently socially.

The paragraph then progresses with descriptions of these similarities and differences. Contrast is created by signal phrases and words such as “although, “on the other hand,” and “unlike.” Words such as “apart” and “differently” also indicate that the organizational pattern of this paragraph is comparison and contrast .

Sample Paragraph 6

• There are many reasons why I enjoy walking tours when visiting new cities. For starters, walking through a city allows the visitor to see the details of an area without having to hurry. This often results in meeting locals and experiencing their lives and traditions first hand. Furthermore, walking tours are flexible and inexpensive because there are no strict schedules or transportation expenses. Travelers taking walking tours are rewarded with firsthand experiences in the places they visit and the opportunity to personally interact with the people who live there.

Because the first sentence begins with “there are,” the reader must move beyond the subject and verb to find the topic. Additionally, this is a complex sentence with an independent and dependent clause connected by “why,” so there may be two topics. Looking at the objects of both clauses, the reader finds “many reasons” and “walking tours.” These two topics are linked together by the controlling idea: the writer enjoys walking tours while visiting new cities for many different reasons.

The signal words build on this idea of “why” with terms such as “results” and “because.” The last sentence then sums up the ultimate effect of walking tours: Travelers are rewarded. This is an example of cause and effect organization.

Sample Paragraph 7

• Hiking can be especially exhilarating during snowy winter months. When my friend and I visited North Carolina last January, we hiked in the Blue Ridge Mountains near the highest peak, Mount Mitchell, which is 6,684 feet above sea level. We first crossed a footbridge over a rapidly moving, ice-cold river and then followed a wooded trail up to a waterfall. Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees. We saw deer and rabbits as we trekked up the path. I assure you that nothing feels better than inhaling crisp mountain air, but the neatest part of hiking in winter, besides the beauty of the mountain, is exhaling and seeing my breath turn to frost when it hits the cold air!

In the first sentence, the topic of the paragraph is “hiking,” and the comment or main idea is that it “can be especially exhilarating during snowy winter months.” Based on this, the reader can expect supporting details to illustrate this exhilaration, but they do not know how it is organized until they look at the signal words that help progress the topic from one idea to the next.

Taking inventory of the signal words, the reader will find several time markers: “When” and “last January” set the narrative in the past while “first” and “then” develop a chronological order of events. The final summarizing sentence about hiking “in winter” reminds the reader of the season.

Within this chronology , signal words are associated with spatial organization: “over,” “up,” “beneath,” “through,” “crunched” (sounded), “saw,” “feels,” and “seeing.” Narratives typically include descriptive elements about the setting. Additionally, the concluding thought contrasts “inhaling” to “exhaling.” The reader can thus conclude that this paragraph has multiple patterns of organization that are intricately connected.

If you find it difficult to write clear and engaging topic sentences, you are not alone. But don’t worry! 

This blog will help you understand topic sentences better with examples. Also, you’ll get step-by-step guide and tips for writing more effective topic sentences. 

So let’s dive in!

On this Page

What is a Topic Sentence in a Paragraph?

A topic sentence is the opening sentence of the body paragraphs of your essay. It introduces the main idea of that paragraph.

So what is the purpose of a topic sentence? 

It serves as a guidepost, indicating the main purpose and point of the paragraph. Essentially, it is a concise and direct statement that captures the essence of what you want to convey.

A topic sentence is defined by the following characteristics:

• It is the first sentence of a paragraph
• It indicates the main idea of the paragraph
• Acts as a signpost and transition sentence, ensuring clarity and cohesiveness of an essay.

Why are Topic Sentences Important? 

Topic sentences are an essential component of body paragraphs , especially in academic writing which is more formal. Here’s why good these sentences are necessary for an essay:

• They help maintain the organization and coherence of the essay. 

Topic sentences act as a roadmap for your essay, providing a clear path for your readers to follow. They establish the main ideas or arguments of each paragraph, allowing your essay to flow logically and coherently. 

By presenting a central focus in each paragraph, they help you maintain a strong sense of organization. Also, they prevent your essay from becoming a jumbled collection of random thoughts.

• They enhance clarity and readability.

Well-crafted topic sentences promote clarity and conciseness in your writing by summarizing the main idea in a concise manner.

Moreover, they serve as signposts that signal the beginning of a particular discussion. This creates a smooth reading experience and reduces the chances of confusion.

• They help the reader skim through the essay.

These sentences provide readers with a preview of what each paragraph will discuss. This helps them grasp the main point before delving into the rest of the paragraph.

They also enable the readers to quickly grasp the content of a paragraph. This makes it easier for them to skim through the main ideas of the essay without reading it word-by-word.

Topic Sentence vs Thesis Statement: Main Differences

Topic sentences are similar to thesis statements as they fulfill a similar purpose: they show the reader what the paragraph or essay is about. 

However, a thesis statement is written at the end of the essay introduction, and it presents the main idea of the entire paper or essay. Whereas, a topic sentence presents the main idea of a specific paragraph, and is the first sentence of that paragraph.

Here are the major differences between topic sentences and thesis statements:

How to Write a Topic Sentence? Here are 4 Simple Steps 

If you think about it, writing such a sentence seems like a simple task. All you have to do is write one line about the idea you’ll discuss, and you’re done. 

Well, it’s not as easy as it sounds. You need to follow some conditions to write good opening lines for your body paragraphs. 

Here are the steps to write engaging topic sentences:

1. Develop your Thesis Statement 

Writing a specific and self-defining thesis statement is the first step in writing an essay. A thesis statement is necessary as it lays out the main points or structure of your entire essay. 

Having a thesis statement helps you figure out what your body paragraphs will be about. This, in turn, helps you identify each paragraphs controlling idea and craft a topic sentence.

2. Identify the Controlling Ideas of Your Body Paragraphs

Once you have a thesis statement for your essay, identify the main idea or central theme of the paragraphs.

Ask yourself, "What is the key point I want to convey in this paragraph?" This will serve as the focus and topic of your paragraph. Moreover, identifying your main points will also help you make an essay outline.

Here’s an example of how you can identify the main ideas of your body paragraphs:

3. Write your Topic Sentence

Now that you know the main idea of each paragraph, you should attempt to write your topic sentences. It is not necessary that you get the sentences right the first time. Try different variations and see which of the sentences explains the paragraph idea in a better way. 

Ensure that your topic sentence relates directly to your thesis statement or the main argument of your essay. The topic sentence should support and reinforce the overall message you want to convey in your writing.

The example below shows topic sentences based on the main ideas identified in step 2:

4. Revise and Make your Topic Sentences Better

A strong topic sentence should be clear, concise, and directly related to your thesis statement. They should also be logically connected to the previous paragraph. It is important that you revise, make them better, and rewrite the sentences as you progress with the paper. 

Make sure that they reflect the main theme of the paragraph and are according to the paragraph’s content. Use appropriate transition words for essays when transitioning from one paragraph to another.

Read on to learn about different types of topic sentences. They will help you to write, rewrite, and revise your opening sentences in the best ways.

What are the Different Types of Topic Sentences?

Here are some common types of topic sentences you can incorporate in your essay.

[Infographic]

• Statement of Fact or Information

This type of topic sentence presents a straightforward statement of fact or information that sets the stage for the paragraph. It provides essential background knowledge or introduces a key concept. 

• Hook or Shocker  

This kind of sentence presents a shocking statement of fact about the paragraph’s key idea. This type of topic sentence aims to grab the reader’s attention and make them want to read more. 

• Illustration or Example

An illustration or example topic sentence provides a specific instance or anecdote to support the main idea of the paragraph. It helps to clarify and reinforce your argument by providing concrete evidence or a real-life scenario. 

• Question or Thought-Provoking Statement  

A topic sentence in the form of a question or thought-provoking statement engages readers by encouraging them to seek an answer. It stimulates curiosity and anticipation for what follows in the paragraph.

Helpful Tips for Writing Better Topic Sentences

• Be Clear and Concise: Focus on expressing the main idea of the paragraph in a concise and direct manner. Avoid unnecessary details or convoluted language that may confuse your readers.
• Consider the Paragraph's Focus: Avoid including multiple ideas or concepts within a single topic sentence. Instead, focus on one central point for each paragraph.
• Vary Your Sentence Structure: To maintain reader interest and engagement, vary the structure of your topic sentences. Experiment with different types, such as simple sentences, rhetorical questions, or even shocking facts.
• Use Strong and Descriptive Language: Choose powerful and descriptive words that accurately capture the essence of your main idea. Avoid vague or generic language that lacks impact. Instead, opt for words that evoke emotions or create vivid imagery.
• Seek Feedback: Consider sharing your writing with others and seeking feedback on your paragraphs. Ask for input on clarity, coherence, transitions, and overall effectiveness.

A great topic sentence directs the reader about the main content of the paragraph. It is brief and engages the reader. 

Remember, mastering the art of writing effective topic sentences takes practice and refinement. As you develop your writing skills, focus on crafting clear and engaging topic sentences that align with your thesis statement.

What is a topic sentence?

A topic sentence states the main point of a paragraph: it serves as a mini-thesis for the paragraph. You might think of it as a signpost for your readers—or a headline—something that alerts them to the most important, interpretive points in your essay. When read in sequence, your essay’s topic sentences will provide a sketch of the essay’s argument. Thus topics sentences help protect your readers from confusion by guiding them through the argument. But topic sentences can also help you to improve your essay by making it easier for you to recognize gaps or weaknesses in your argument.

Where do topic sentences go?

Topic sentences usually appear at the very beginning of paragraphs. In the following example from Anatomy of Criticism , Northrop Frye establishes the figure of the tragic hero as someone more than human, but less than divine. He backs up his claim with examples of characters from literature, religion and mythology whose tragic stature is a function of their ability to mediate between their fellow human beings and a power that transcends the merely human:

The tragic hero is typically on top of the wheel of fortune, half-way between human society on the ground and the something greater in the sky. Prometheus, Adam, and Christ hang between heaven and earth, between a world of paradisal freedom and a world of bondage. Tragic heroes are so much the highest points in their human landscape that they seem the inevitable conductors of the power about them, great trees more likely to be struck by lightning than a clump of grass. Conductors may of course be instruments as well as victims of the divine lightning: Milton’s Samson destroys the Philistine temple with himself, and Hamlet nearly exterminates the Danish court in his own fall.

The structure of Frye’s paragraph is simple yet powerful: the topic sentence makes an abstract point, and the rest of the paragraph elaborates on that point using concrete examples as evidence.

Does a topic sentence have to be at the beginning of a paragraph?

No, though this is usually the most logical place for it. Sometimes a transitional sentence or two will come before a topic sentence:

We found in comedy that the term bomolochos or buffoon need not be restricted to farce, but could be extended to cover comic characters who are primarily entertainers, with the function of increasing or focusing the comic mood. The corresponding contrasting type is the suppliant, the character, often female, who presents a picture of unmitigated helplessness and destitution. Such a figure is pathetic, and pathos, though it seems a gentler and more relaxed mood than tragedy, is even more terrifying. Its basis is the exclusion of an individual from the group; hence it attacks the deepest fear in ourselves that we possess—a fear much deeper than the relatively cosy and sociable bogey of hell. In the suppliant pity and terror are brought to the highest possible pitch of intensity, and the awful consequences of rejecting the suppliant for all concerned is a central theme of Greek tragedy.

The context for this passage is an extended discussion of the characteristics of tragedy. In this paragraph, Frye begins by drawing a parallel between the figure of the buffoon in comedy and that of the suppliant in tragedy. His discussion of the buffoon occurred in a earlier section of the chapter, a section devoted to comedy. The first sentence of the current paragraph is transitional: it prepares the way for the topic sentence. The delayed topic sentence contributes to the coherence of Frye’s discussion by drawing an explicit connection between key ideas in the book. In essays, the connection is usually between the last paragraph and the current one.

Sometimes writers save a topic sentence for the end of a paragraph. You may, for example, occasionally find that giving away your point at the beginning of a paragraph does not allow you to build your argument toward an effective climax.

How do I come up with a topic sentence? And what makes a good one?

Ask yourself what’s going on in your paragraph. Why have you chosen to include the information you have? Why is the paragraph important in the context of your argument? What point are you trying to make?

Relating your topic sentences to your thesis can help strengthen the coherence of your essay. If you include a thesis statement in your introduction, then think of incorporating a keyword from that statement into the topic sentence. But you need not be overly explicit when you echo the thesis statement. Better to be subtle rather than heavy-handed. Do not forget that your topic sentence should do more than just establish a connection between your paragraph and your thesis. Use a topic sentence to show how your paragraph contributes to the development of your argument by moving it that one extra step forward. If your topic sentence merely restates your thesis, then either your paragraph is redundant or your topic sentence needs to be reformulated. If several of your topic sentences restate your thesis, even if they do so in different words, then your essay is probably repetitive.

Does every paragraph need one?

No, but most do. Sometimes a paragraph helps to develop the same point as in the previous paragraph, and so a new topic sentence would be redundant. And sometimes the evidence in your paragraph makes your point so effectively that your topic sentence can remain implicit. But if you are in doubt, it’s best to use one.

Table of Contents

A topic sentence summarizes the main idea or the purpose of a paragraph.

In an essay, topic sentences serve an organizational purpose similar to a thesis statement but on a smaller scale; a topic sentence helps guide the organization of a single paragraph while a thesis statement guides the organization of the entire essay. A topic sentence may be placed at the beginning, middle, or end of a paragraph depending upon the way the writer chooses to organize the paragraph.

What are the functions of a topic sentence?

A topic sentence functions in several important ways:

• It informs the reader of the paragraph’s direction

The topic sentence announces the direction of the paragraph’s conversation. With the help of an effective topic sentence, readers will better understand what the paragraph will be about.

• It guides the reader through the major points that support the thesis statement

Since each paragraph—or a group of paragraphs—elaborates on a part of the thesis statement, a topic sentence can help clarify the relationship between the paragraph and the thesis statement. Clearly worded topic sentences may help readers find the paper’s position or argument more convincing.

• It places boundaries on the paragraph’s content

The body of the paragraph provides support for the topic sentence. The paragraph should only include evidence and details that relate directly to the boundary established by the topic sentence.

Let’s look at an example:

Topic sentence: Specially trained dogs provide valuable services for various law enforcement agencies.

Details within the paragraph:

• Drug Enforcement Administration officers use dogs to find various types of drugs.
• Some dogs are trained to search for and locate bombs and other weapons for the Bureau of Alcohol, Tobacco and Firearms.
• Police dogs can be used to track missing people or fugitives.
• Cadaver dogs are trained to ignore the scent of live humans and search for human remains.

When the topic sentence prefaces the sentences with supporting details, the purpose of the paragraph is clearer to the reader. Together, the topic sentence and the body sentences create a well-organized and easy to follow paragraph:

Specially trained dogs provide valuable services for various law enforcement agencies. The Drug Enforcement Administration trains dogs to find even trace amounts of various types of illegal substances. The Bureau of Alcohol, Tobacco, and Firearms uses dogs to search for and locate bombs and other weapons, especially at large public events or arenas. Additionally, several local and federal agencies use dogs to track missing people or fugitives who may be found in a specific, localized area. Cadaver dogs, similarly, are trained to ignore the scent of live humans and search for human remains. These dogs are valuable assets to our country’s law enforcement organizations.

Where should the topic sentence be placed within a paragraph?

Your instructor may have guidelines for you about where to place topic sentences. If it is up to you, the topic sentence may appear:

• At the beginning. In many writing situations, the author places the topic sentence at the beginning of the paragraph. Readers often expect cues related to the paragraph’s focus, claim, and main idea. In this position, the topic sentence makes an initial point and the remainder of the paragraph provides relevant supporting details.
• In the middle. In a few writing situations, the author may use the first sentence (or two) in a paragraph to act as a transition between paragraphs. The topic sentence that follows the transitional sentence(s) summarizes the paragraph’s main idea and helps provide unity to its content. In this position, the topic sentence links the supporting details presented before and after it.
• At the end. In some writing situations, the author may place the topic sentence at the end of the paragraph. Groundwork laid at the beginning of the paragraph can be built upon until it culminates at the end. Or, in a long or complex paragraph, the author may choose to restate the topic sentence in the form of a concluding sentence to remind the reader of the paragraph’s main point.

When might a topic sentence be unnecessary?

If they are not required by an instructor, there are a few instances when a topic sentence might be unnecessary, including when:

• The train of thought continues from the previous paragraph. Writers may find they have a lot to say about a sub-point in their essay and the number of supporting details could result in unwieldy paragraph length. When a previously developed idea spills into a new paragraph, a topic sentence may not be needed for the resulting new paragraph.
• The paragraph narrates a series of events. Writers may become narrators in some settings; hence, this transmission of events or experiences may speak for itself and a topic sentence could get in the way.
• The main idea of the paragraph is obvious Writers may sometimes present reliable, convincing evidence in such a way that the point of the paragraph is obvious and a topic sentence becomes unnecessary.

When during writing should the topic sentence be identified?

Because writing is a thoughtful, constructive process, writers may not always know what form their thoughts will take until they make it onto the page. This process involves a developmental progression that usually includes several drafts. Writers may identify topic sentences at different points during the writing process. Sometimes writers know right away what the topic sentence looks like and where it fits within the paragraph. Other times, they need to look at earlier drafts and analyze the main point of the paragraph. Then, a decision can be reached whether or not a topic sentence is necessary and, if so, where it should be placed.

How do I write or revise a topic sentence?

When writing or revising a topic sentence, consider whether the topic sentence:

• concisely summarizes the main idea or purpose of the paragraph?
• effectively guides the organization of the paragraph’s ideas?
• clearly announces the direction of the paragraph’s conversation?
• actively supports the relationship between the paragraph’s ideas and the essay’s thesis statement?
• adequately prepares the way for the content of the paragraph?
• firmly establishes boundaries for the supporting details and evidence presented in the paragraph?

What is a Topic Sentence?

A topic sentence is the first sentence of a paragraph in an essay that introduces the main idea or topic of that paragraph. It serves as a roadmap for the reader, letting them know what to expect in the upcoming paragraph. 

Purpose of Topic Sentence

The purpose of a topic sentence is to clearly and concisely convey the main point of the paragraph to the reader.

• Is specific and focused , avoiding vague or overly general statements.
• Introduces the main point and is typically located at the beginning of the paragraph or essay.
• Presents a claim or position that is arguable or debatable, which the rest of the paragraph or essay will support.
• Can be a complete sentence or a concise phrase that effectively conveys the main idea.
• Is relevant to the thesis statement and overall topic of the essay.
• Engages the reader by creating interest and highlighting the significance of the topic.
• Is well-written and avoids grammar and spelling errors.
• Provides a roadmap for the rest of the paragraph or essay by indicating what will be covered.

Types of Topic Sentences

There are several different types of topic sentences that can be used in writing to introduce the reader through a paragraph or essay.

Simple Statement Topic Sentence This is the most common type of topic sentence, which straightforwardly states the main point or idea of the paragraph or essay.

Example: The rise of social media has revolutionized the way people communicate with each other.

Complex Topic Sentence This type of topic sentence is more nuanced and may require some explanation or elaboration to fully understand.

Example: While the rise of social media has had many positive effects on communication, it has also led to concerns about privacy and online harassment.

Pivot Topic Sentence A pivot topic sentence begins by connecting the current paragraph or idea to the previous one, before pivoting to introduce a new point or idea.

Example: Building on the idea of social media's impact on communication, it is important to consider how it has also affected business and marketing strategies.

Question Topic Sentence A question topic sentence poses a question that the rest of the paragraph or essay will answer or explore.

Example: How has social media changed the way businesses interact with customers and advertise their products?

Command Topic Sentence This type of topic sentence gives a directive or instruction, often used in persuasive or argumentative essays.

Example: Support local businesses by shopping at independently owned stores instead of large chains.

How to Write a Topic Sentence?

Here are a few instructions to help you write a good topic sentence. 

Step#1 Clearly State The Main Idea

A topic sentence is the first paragraph of the paragraph. It must clearly explain the particular subject that would be discussed in the paragraph. This should be stated in very clear language so that the reader can easily understand the idea. 

Also, it should include a bit of your personal opinion and also the main idea. 

Step#2 Hook Your Reader

Grab your reader's attention with an intriguing topic sentence. It would excite and make the reader curious about the content and convince them to read the particular part. 

Look out for some amazing hook examples and see what fits your essay type. 

Use a meaningful and relevant question or a fact as a topic sentence of the paragraph. Make sure that you have identified your audience and are developing everything accordingly. 

Step#3 Keep It Short and Precise

The paragraph topic sentence must be expressive enough that a reader understands your point of view effortlessly. This is only possible if you keep everything to the point, short, and meaningful. 

Choose the words in such a way that they help you express your idea in an ideal way. Avoid using complex sentences and use independent clauses.  

A topic sentence acts as a link between a paragraph and the main thesis statement. It should be specific and connected to the overall essay. Keeping it short and precise helps maintain the paragraph's flow and its relevance to the rest of the writing.

Step#4 Give A Reasonable Opinion

The body paragraph explains a topic sentence. This is why it is important that you should write this sentence in such a way that it can be explained in the paragraph.  If you are mentioning a fact in the topic statement, make sure that you have authentic evidence to support it. 

While the topic sentence is an integral part of the paragraph, it should stand out and possess a distinctiveness that sets it apart from the other sentences. This can be achieved by employing transition words and establishing connections between sentences.

Step#5 Use The Topic Sentence As A Transition

The topic sentences that serve as transition sentences can be considered a guide for the readers. This way, they can help the reader to move through the essay in a flow. 

Write this sentence in such a way that it creates a gateway between the previous paragraph and the rest of the essay. Moreover, it will also help keep the essay organized, and the reader understands the point of a paragraph.

Step#6 Look For Some Good Examples

Examples can help you learn a thing in a better way. If you are new to writing topic sentences, it can help to look at some examples. Find some great examples of topic sentences relevant to your essay topic.

Difference Between Topic Sentence and Thesis Sentence

Here's a table outlining the differences between a topic sentence and a thesis statement:

Good Topic Sentence Examples

Here are ten examples of good topic sentences:

•  "Despite the advancements in technology, traditional forms of communication are still essential in today's society."
• "The theme of power is prevalent throughout Shakespeare's play, Macbeth."
• "In recent years, there has been a growing concern over the impact of climate change on our planet."
• "The legalization of marijuana has been a topic of debate for many years." "Education is the key to success in life."
• "The rise of social media has greatly impacted the way we communicate with one another."
• "The effects of childhood trauma can have a lasting impact on mental health."
• "The concept of justice is explored in depth in Harper Lee's To Kill a Mockingbird."
• "Eating a balanced diet is crucial for maintaining good health."
• "The Industrial Revolution had a profound effect on the world as we know it today."

The Bottom Line!

An opening sentence is crucial to grab your reader's attention and set the tone for your piece of writing. The topic sentence introduces the controlling idea and acts as an important sentence in the essay outline. 

Effective topic sentences are necessary for a well-structured and organized essay. It's an integral part of the writing process that should not be overlooked. 

Make sure to spend time crafting a compelling topic sentence that clearly conveys your main point and guides your readers throughout your essay. You can even take ideas from an AI essay generator to get started.

A topic sentence is a  sentence , sometimes at the beginning of a paragraph , that states or suggests the main idea (or topic ) of a paragraph.

Not all paragraphs begin with topic sentences. In some, the topic sentence appears in the middle or at the end. In others, the topic sentence is implied or absent altogether.

Examples and Observations

• " Salva and the other boys made cows out of clay. The more cows you made, the richer you were. But they had to be fine, healthy animals. It took time to make a lump of clay look like a good cow. The boys would challenge each other to see who could make the most and best cows." (Linda Sue Park, A Long Walk to Water . Clarion, 2010)
• " Momma bought two bolts of cloth each year for winter and summer clothes. She made my school dresses, underslips, bloomers, handkerchiefs, Bailey's shirts, shorts, her aprons, house dresses and waists from the rolls shipped to Stamps by Sears and Roebuck. . . ." (Maya Angelou, I Know Why the Caged Bird Sings . Random House, 1969)
• " You discover what it is like to be hungry. With bread and margarine in your belly, you go out and look into the shop windows. Everywhere there is food insulting you in huge, wasteful piles; whole dead pigs, baskets of hot loaves, great yellow blocks of butter, strings of sausages, mountains of potatoes, vast Gruyère cheeses like grindstones. A snivelling self-pity comes over you at the sight of so much food. You plan to grab a loaf and run, swallowing it before they catch you; and you refrain, from pure funk." (George Orwell, Down and Out in Paris and London . Victor Gollancz, 1933)
• " The flavor that salt imparts to food is just one of the attributes that manufacturers rely on. For them, salt is nothing less than a miracle worker in processed foods. It makes sugar taste sweeter. It adds crunch to crackers and frozen waffles. It delays spoilage so that the products can sit longer on the shelf. And, just as importantly, it masks the otherwise bitter or dull taste that hounds so many processed foods before salt is added." (Michael Moss, Salt, Sugar, Fat: How the Food Giants Hooked Us . Random House, 2013)
• " The very idea of retirement is a relatively new invention. For most of human history, people worked until they died or were too infirm to lift a finger (at which point they died pretty fast anyway). It was the German statesman Otto von Bismarck who first floated the concept, in 1883, when he proposed that his unemployed countrymen over the age of 65 be given a pension. This move was designed to fend off Marxist agitation—and to do so on the cheap, since few Germans survived to that ripe old age." (Jessica Bruder, "The End of Retirement." Harper's , August 2014)
• " Grandma's room I regarded as a dark den of primitive rites and practices. On Friday evenings whoever was home gathered at her door while she lit her Sabbath candles. . . ."  (E.L. Doctorow, World's Fair . Random House, 1985)
• " Genealogy is an ancient human preoccupation. The God of Hebrew Scripture promised Abraham descendants beyond number, like the stars in the sky and the sand on the seashore. The apostles Matthew and Luke claim that Abraham's lineage went on to include King David and eventually Jesus, though the specifics of their accounts are contradictory. Muslims trace Mohammed's line back through Abraham, to Adam and Eve." (Maud Newton, "America's Ancestry Craze." Harper's , June 2014)
• " O nce, in a restaurant in Italy with my family, I occasioned enormous merriment, as a nineteenth-century humorist would have put it, by confusing two Italian words. I thought I had, very suavely, ordered for dessert fragoline —those lovely little wild strawberries. Instead, I seem to have asked for fagiolini —green beans. The waiter ceremoniously brought me a plate of green beans with my coffee, along with the flan and the gelato for the kids. The significant insight the mistake provided—arriving mere microseconds after the laughter of those kids, who for some reason still bring up the occasion, often—was about the arbitrary nature of language: the single 'r' rolled right makes one a master of the trattoria, an 'r' unrolled the family fool. . . ." (Adam Gopnik, "Word Magic." The New Yorker , May 26, 2014)
• " In seventeenth-century Europe, the transformation of man into soldier took on a new form, more concerted and disciplined, and far less pleasant, than wine. New recruits and even seasoned veterans were endlessly drilled, hour after hour, until each man began to feel himself part of a single, giant fighting machine. . . ." (Barbara Ehrenreich, Blood Rites: Origins and History of the Passions of War . Henry Holt and Company, 1997)
• " What is the appeal of train travel? Ask almost any foamer, and he or she will invariably answer, 'The romance of it!' But just what this means, they cannot really say. It's tempting to think that we are simply equating romance with pleasure, with the superior comfort of a train, especially seated up high in the observation cars. . . ." (Kevin Baker, "21st Century Limited: The Lost Glory of America's Railroads." Harper's , July 2014)
• " Because science fiction spans the spectrum from the plausible to the fanciful, its relationship with science has been both nurturing and contentious. For every author who meticulously examines the latest developments in physics or computing, there are other authors who invent 'impossible' technology to serve as a plot device (like Le Guin’s faster-than-light communicator, the ansible) or to enable social commentary, the way H. G. Wells uses his time machine to take the reader to the far future to witness the calamitous destiny of the human race." (Eileen Gunn, "Brave New Words." Smithsonian , May 2014)
• " I passed all the other courses that I took at my university, but I could never pass botany. . . ." (James Thurber, My Life and Hard Times . Harper & Row, 1933)
• " What is there about this wonderful woman? From next door, she comes striding, down the lawn, beneath the clothesline, laden with cookies she has just baked, or with baby togs she no longer needs, and one's heart goes out. Pops out. The clothesline, the rusted swing set, the limbs of the dying elm, the lilacs past bloom are lit up like rods of neon by her casual washday energy and cheer, a cheer one has done nothing to infuse." (John Updike, "One's Neighbor's Wife." Hugging the Shore: Essays and Criticism . Knopf, 1983)
• " Television. Why do I watch it? The parade of politicians every evening: I have only to see the heavy, blank faces so familiar since childhood to feel gloom and nausea. . . ." (J.M. Coetzee, Age of Iron . Random House, 1990)
• " Anyone who has made the coast-to-coast journey across America, whether by train or by car, has probably passed through Garden City, but it is reasonable to assume that few travelers remember the event. It seems just another fair-sized town in the middle--almost the exact middle--of the continental United States. . . ." (Truman Capote, In Cold Blood . Random House, 1966)
• " Rodeo, like baseball, is an American sport and has been around almost as long. . . ." (Gretel Ehrlich, The Solace of Open Spaces . Viking Penguin, 1985)
• " What a piece of work is a book! I am not talking about writing or printing. I am talking about the codex we may leaf through, that may be put away on a shelf for whole centuries and will remain there, unchanged and handy. . . ." (William Golding, A Moving Target . Farrar, Straus and Giroux, 1982)

Characteristics of an Effective Topic Sentence

• "A good topic sentence is concise and emphatic . It is no longer than the idea requires, and it stresses the important word or phrase. Here, for instance, is the topic sentence which opens a paragraph about the collapse of the stock market in 1929: "The Bull Market was dead."(Frederick Lewis Allen) Notice several things. (1) Allen's sentence is brief . Not all topics can be explained in six words, but whether they take six or sixty, they should be phrased in no more words than are absolutely necessary. (2) The sentence is clear and strong: you understand exactly what Allen means. (3) It places the keyword—'dead'—at the end, where it gets heavy stress and leads naturally into what will follow. . . . (4) The sentence stands first in the paragraph. This is where topic sentences generally belong: at or near the beginning." (Thomas S. Kane, The New Oxford Guide to Writing . Oxford Univ. Press, 1988)

Positioning a Topic Sentence

"If you want readers to see your point immediately, open with the topic sentence . This strategy can be particularly useful in letters of application or in argumentative writing. . . . "When specific details lead up to a generalization, putting the topic sentence at the end of the paragraph makes sense. . . . "Occasionally a paragraph's main idea is so obvious that it does not need to be stated explicitly in a topic sentence." (Andrea Lunsford, The St. Martin's Handbook . Bedford/St. Martin's, 2008)

Guidelines for Composing Topic Sentences

"The topic sentence is the most important sentence in your paragraph. Carefully worded and restricted, it helps you generate and control your information. An effective topic sentence also helps readers grasp your main idea quickly. As you draft your paragraphs, pay close attention to the following three guidelines:

• Make sure you provide a topic sentence. . . .
• Put your topic sentence first.
• Be sure your topic sentence is focused. If restricted, a topic sentence discusses only one central idea. A broad or unrestricted topic sentence leads to a shaky, incomplete paragraph for two reasons:
• The paragraph will not contain enough information to support the topic sentence .
• A broad topic sentence will not summarize or forecast specific information in the paragraph."

(Philip C. Kolin, Successful Writing at Work , 9th ed. Wadsworth, 2010)

Testing for Topic Sentences

"When testing your article for topic sentences , you should be able to look at each paragraph and say what the topic sentence is. Having said it, look at all the other sentences in the paragraph and test them to make sure they support it. . . .

"If you find that you have come up with the same topic sentence more than once, you have two paragraphs doing the same work. Cut one of them out.

"If you find a paragraph that has several sentences that don't support the topic sentence, see if all the outlaw sentences support some other topic sentence and turn the one paragraph into two." (Gary Provost, "How to Test Your Articles for the 8 Essentials of Nonfiction." Handbook of Magazine Article Writing , ed. by Jean M. Fredette. Writer's Digest Books, 1988)

Frequency of Topic Sentences

"Teachers and textbook writers should exercise caution in making statements about the frequency with which contemporary professional writers use simple or even explicit topic sentences in expository paragraphs. It is abundantly clear that students should not be told that professional writers usually begin their paragraphs with topic sentences."  (Richard Braddock, "The Frequency and Placement of Topic Sentences in Expository Prose." Research in the Teaching of English . Winter 1974)

TOPIC SENTENCE/ In his numerous writings, Marx critiques capitalism by identifying its flaws. ANALYSIS OF EVIDENCE/ By critiquing the political economy and capitalism, Marx implores his reader to think critically about their position in society and restores awareness in the proletariat class. EVIDENCE/ To Marx, capitalism is a system characterized by the “exploitation of the many by the few,” in which workers accept the exploitation of their labor and receive only harm of “alienation,” rather than true benefits ( MER 487). He writes that “labour produces for the rich wonderful things – but for the worker it produces privation. It produces palaces—but for the worker, hovels. It produces beauty—but for the worker, deformity” (MER 73). Marx argues capitalism is a system in which the laborer is repeatedly harmed and estranged from himself, his labor, and other people, while the owner of his labor – the capitalist – receives the benefits ( MER 74). And while industry progresses, the worker “sinks deeper and deeper below the conditions of existence of his own class” ( MER 483).  ANALYSIS OF EVIDENCE/ But while Marx critiques the political economy, he does not explicitly say “capitalism is wrong.” Rather, his close examination of the system makes its flaws obvious. Only once the working class realizes the flaws of the system, Marx believes, will they - must they - rise up against their bourgeois masters and achieve the necessary and inevitable communist revolution.

Not every paragraph will be structured exactly like this one, of course. But as you draft your own paragraphs, look for all three of these elements: topic sentence, evidence, and analysis.

Topic Sentence - FAQ

How long is a topic sentence.

Generally, a topic sentence should not be more than three lines long. However, you can also make it at least 30 words long. All you need to do is make sure that the sentence contains all the three primary parts mentioned above. It is also worth noting that you do not have to hit the thirty words mark. Ensure it is neither too long nor too short.

Tip: If you are done with your academic work, we can help you with dissertation printing !

Can a topic sentence be a question?

Unlike the thesis statement, this sentence can be written in the form of a question. In such a case, the rest of the paragraph will be written as a response or answer. This means you have to make sure that the sentence, even if it is in question form, presents the paragraph’s main point.

Why are topic sentences important?

This sentence is important because it helps you keep your writing focused. It also guides your instructor or teacher through your argument or ideas. In an essay or paper, this sentence helps focus the instructor on your paper’s main idea. It also helps clarify the paragraph to you and the reader.

Is there a right and wrong way to write the topic sentence?

The most straightforward answer to this question is YES. There is a right and wrong way to write this part of your paper. You have to make sure the sentence features the three main parts, it has to be thorough, not too long or short, and it needs to focus on the paragraph’s main idea. Anything without the elements mentioned above would be wrong.

Topic Sentence: Definition

A topic sentence is a sentence used as an introduction to a paragraph. Its role is to present the primary topic in a paragraph and not an entire project like a thesis statement . This sentence is usually specific and has a narrower focus as compared to a thesis statement. It usually appears in or close to the first sentence of the paragraph.

The three main parts

The topic – this part is written to tell the reader what the paragraph’s topic is. It is usually the first part of the topic sentence.

The opinion – this is the middle part of the topic sentence, and it contains your thoughts about the topic at hand.

The supporting sentence – this part details and gives more information about the topic. It also contains an explanation that supports the idea in the topic.

These three parts work together to make up an effective topic sentence. It is important to note that while these three parts are mandatory, this sentence consists of more than stating the paragraph’s subject.

Writing a strong topic sentence

When writing a research paper or any other academic writing, you need to make sure that every paragraph features this sentence. The topic sentence expresses the components or the main idea of the paragraph. Since it is an integral part of your writing, it needs to be written correctly. Below is a step by step guide on how to write a strong topic sentence:

Clearly state the main idea

The first thing you should do is determine what concept you want to display in the paragraph. Once you have done that, you can find a way to state the main idea. The idea needs to be precise. However, this does not mean that you can use many sentences to bring it out. You must include your topic in the sentence, an opinion and your controlling idea.

Make sure the opinion part of the sentence is reasonable. It should be an idea that can be supported by concrete evidence as required by most universities and learning institutions. Note that this is not an invitation for you to announce your topic like you would in a speech or public speaking.

Create a balance between specifics and the overall idea

Make sure the topic sentence relates to the paragraph to the general concept in your thesis statement or essay. This means that it shouldn’t be too vague or too narrow. The wise thing to do would be to create a right balance between the paragraph context and the general idea.

Make it enjoyable

Remember that the topic sentence is the first thing your reader or instructor will read before diving into your paragraphs. Therefore, if you want to entice your reader into enthusiastically reading your work, then you should make it enjoyable. Use it to hook your reader. Note that you will be creating a topic sentence for each paragraph.

Therefore, creating incredible and enjoyable sentences will keep your reader interested throughout your paper. You can do this by using detail, dialogue, describing a character, and trying as much as possible to avoid rhetorical questions.

Keep it short

As mentioned earlier, an ideal topic sentence should not exceed 30 words or three lines long. It should not be too long that it has your reader hunting its point. It would help if you made sure that the point of the sentence is precise. Remember that this sentence will act as a middle ground into your paragraph. Additionally, keeping your topic sentence short will help maintain the flow of your paragraph.

Topic sentences as transitions

As mentioned earlier, every paragraph needs to have a topic sentence. That said, when you write this sentence for each paragraph, you need to ask yourself whether or not the point relates to what you wrote in the preceding section. Therefore, you must use transition words. These words will help you show a connection between your thoughts and ideas.

Additionally, if you are using the paragraph to explain its predecessor further, then the right thing to do would be to use words that show emphasis. Such words include furthermore , indeed , and also .

On the other hand, if the paragraph contains a different aspect of the same subject, you can start this sentence as a summary of the previous paragraph. You can also use it to anticipate the new data you look to include in the new paragraph.

You may want to use a new paragraph to compare the former section’s information in some instances. In such a case, in the sentence topic, you need to use words that highlight conflict. Such words include in contrast, however, on the other hand, and yet, to name a few. You can also form this sentence as a question to show a difference in ideas.

In a Nutshell

A topic sentence is the opening part of a paragraph. It helps give your readers the general idea of what the rest of the paragraph will be about. In a research paper or any other type of academic paper, every paragraph needs this sentence. A good topic sentence should contain the topic, opinion and supporting sentence. The topic sentence acts as a guide to the subject of the paragraph, and it also relates to the main idea of the paper.

Paragraph structure

Jump to content on this page:

“An appropriate use of paragraphs is an essential part of writing coherent and well-structured essays.” Don Shiach,   How to write essays

• A topic sentence – what is the overall point that the paragraph is making?
• Evidence that supports your point – this is usually your cited material.
• Explanation of why the point is important and how it helps with your overall argument.
• A link (if necessary) to the next paragraph (or to the previous one if coming at the beginning of the paragraph) or back to the essay question.

This is a good order to use when you are new to writing academic essays - but as you get more accomplished you can adapt it as necessary. The important thing is to make sure all of these elements are present within the paragraph.

The sections below explain more about each of these elements.

The topic sentence (Point)

This should appear early in the paragraph and is often, but not always, the first sentence.  It should clearly state the main point that you are making in the paragraph. When you are planning essays, writing down a list of your topic sentences is an excellent way to check that your argument flows well from one point to the next.

This is the evidence that backs up your topic sentence. Why do you believe what you have written in your topic sentence? The evidence is usually paraphrased or quoted material from your reading . Depending on the nature of the assignment, it could also include:

• Your own data (in a research project for example).
• Personal experiences from practice (especially for Social Care, Health Sciences and Education).
• Personal experiences from learning (in a reflective essay for example).

Any evidence from external sources should, of course, be referenced.

Explanation (analysis)

This is the part of your paragraph where you explain to your reader why the evidence supports the point and why that point is relevant to your overall argument. It is where you answer the question 'So what?'. Tell the reader how the information in the paragraph helps you answer the question and how it leads to your conclusion. Your analysis should attempt to persuade the reader that your conclusion is the correct one.

These are the parts of your paragraphs that will get you the higher marks in any marking scheme.

Links are optional but it will help your argument flow if you include them. They are sentences that help the reader understand how the parts of your argument are connected . Most commonly they come at the end of the paragraph but they can be equally effective at the beginning of the next one. Sometimes a link is split between the end of one paragraph and the beginning of the next (see the example paragraph below).

Length of a paragraph

Academic paragraphs are usually between 200 and 300 words long (they vary more than this but it is a useful guide). The important thing is that they should be long enough to contain all the above material. Only move onto a new paragraph if you are making a new point. 

Many students make their paragraphs too short (because they are not including enough or any analysis) or too long (they are made up of several different points).

Example of an academic paragraph

Using storytelling in educational settings can enable educators to connect with their students because of inborn tendencies for humans to listen to stories.   Written languages have only existed for between 6,000 and 7,000 years (Daniels & Bright, 1995) before then, and continually ever since in many cultures, important lessons for life were passed on using the oral tradition of storytelling. These varied from simple informative tales, to help us learn how to find food or avoid danger, to more magical and miraculous stories designed to help us see how we can resolve conflict and find our place in society (Zipes, 2012). Oral storytelling traditions are still fundamental to native American culture and Rebecca Bishop, a native American public relations officer (quoted in Sorensen, 2012) believes that the physical act of storytelling is a special thing; children will automatically stop what they are doing and listen when a story is told. Professional communicators report that this continues to adulthood (Simmons, 2006; Stevenson, 2008).   This means that storytelling can be a powerful tool for connecting with students of all ages in a way that a list of bullet points in a PowerPoint presentation cannot. The emotional connection and innate, almost hardwired, need to listen when someone tells a story means that educators can teach memorable lessons in a uniquely engaging manner that is   common to all cultures. 

The cross-cultural element of storytelling can be seen when reading or listening to wisdom tales from around the world...

What is a paragraph?

A paragraph is a collection of related sentences dealing with a single topic. Learning to write good paragraphs will help you as a writer stay on track during your drafting and revision stages. Good paragraphing also greatly assists your readers in following a piece of writing. You can have fantastic ideas, but if those ideas aren't presented in an organized fashion, you will lose your readers (and fail to achieve your goals in writing).

The Basic Rule: Keep one idea to one paragraph

The basic rule of thumb with paragraphing is to keep one idea to one paragraph. If you begin to transition into a new idea, it belongs in a new paragraph. There are some simple ways to tell if you are on the same topic or a new one. You can have one idea and several bits of supporting evidence within a single paragraph. You can also have several points in a single paragraph as long as they relate to the overall topic of the paragraph. If the single points start to get long, then perhaps elaborating on each of them and placing them in their own paragraphs is the route to go.

Elements of a paragraph

To be as effective as possible, a paragraph should contain each of the following: Unity, Coherence, A Topic Sentence, and Adequate Development. As you will see, all of these traits overlap. Using and adapting them to your individual purposes will help you construct effective paragraphs.

The entire paragraph should concern itself with a single focus. If it begins with one focus or major point of discussion, it should not end with another or wander within different ideas.

Coherence is the trait that makes the paragraph easily understandable to a reader. You can help create coherence in your paragraphs by creating logical bridges and verbal bridges.

Logical bridges

• The same idea of a topic is carried over from sentence to sentence
• Successive sentences can be constructed in parallel form

Verbal bridges

• Key words can be repeated in several sentences
• Synonymous words can be repeated in several sentences
• Pronouns can refer to nouns in previous sentences
• Transition words can be used to link ideas from different sentences

A topic sentence

A topic sentence is a sentence that indicates in a general way what idea or thesis the paragraph is going to deal with. Although not all paragraphs have clear-cut topic sentences, and despite the fact that topic sentences can occur anywhere in the paragraph (as the first sentence, the last sentence, or somewhere in the middle), an easy way to make sure your reader understands the topic of the paragraph is to put your topic sentence near the beginning of the paragraph. (This is a good general rule for less experienced writers, although it is not the only way to do it). Regardless of whether you include an explicit topic sentence or not, you should be able to easily summarize what the paragraph is about.

Adequate development

The topic (which is introduced by the topic sentence) should be discussed fully and adequately. Again, this varies from paragraph to paragraph, depending on the author's purpose, but writers should be wary of paragraphs that only have two or three sentences. It's a pretty good bet that the paragraph is not fully developed if it is that short.

Some methods to make sure your paragraph is well-developed:

• Use examples and illustrations
• Cite data (facts, statistics, evidence, details, and others)
• Examine testimony (what other people say such as quotes and paraphrases)
• Use an anecdote or story
• Define terms in the paragraph
• Compare and contrast
• Evaluate causes and reasons
• Examine effects and consequences
• Analyze the topic
• Describe the topic
• Offer a chronology of an event (time segments)

How do I know when to start a new paragraph?

You should start a new paragraph when:

• When you begin a new idea or point. New ideas should always start in new paragraphs. If you have an extended idea that spans multiple paragraphs, each new point within that idea should have its own paragraph.
• To contrast information or ideas. Separate paragraphs can serve to contrast sides in a debate, different points in an argument, or any other difference.
• When your readers need a pause. Breaks between paragraphs function as a short "break" for your readers—adding these in will help your writing be more readable. You would create a break if the paragraph becomes too long or the material is complex.
• When you are ending your introduction or starting your conclusion. Your introductory and concluding material should always be in a new paragraph. Many introductions and conclusions have multiple paragraphs depending on their content, length, and the writer's purpose.

Transitions and signposts

Two very important elements of paragraphing are signposts and transitions. Signposts are internal aids to assist readers; they usually consist of several sentences or a paragraph outlining what the article has covered and where the article will be going.

Transitions are usually one or several sentences that "transition" from one idea to the next. Transitions can be used at the end of most paragraphs to help the paragraphs flow one into the next.

How to Write an Essay Introduction | 4 Steps & Examples

Published on February 4, 2019 by Shona McCombes . Revised on July 23, 2023.

A good introduction paragraph is an essential part of any academic essay . It sets up your argument and tells the reader what to expect.

The main goals of an introduction are to:

• Catch your reader’s attention.
• Give background on your topic.
• Present your thesis statement —the central point of your essay.

This introduction example is taken from our interactive essay example on the history of Braille.

The invention of Braille was a major turning point in the history of disability. The writing system of raised dots used by visually impaired people was developed by Louis Braille in nineteenth-century France. In a society that did not value disabled people in general, blindness was particularly stigmatized, and lack of access to reading and writing was a significant barrier to social participation. The idea of tactile reading was not entirely new, but existing methods based on sighted systems were difficult to learn and use. As the first writing system designed for blind people’s needs, Braille was a groundbreaking new accessibility tool. It not only provided practical benefits, but also helped change the cultural status of blindness. This essay begins by discussing the situation of blind people in nineteenth-century Europe. It then describes the invention of Braille and the gradual process of its acceptance within blind education. Subsequently, it explores the wide-ranging effects of this invention on blind people’s social and cultural lives.

Step 1: hook your reader, step 2: give background information, step 3: present your thesis statement, step 4: map your essay’s structure, step 5: check and revise, more examples of essay introductions, other interesting articles, frequently asked questions about the essay introduction.

Your first sentence sets the tone for the whole essay, so spend some time on writing an effective hook.

Avoid long, dense sentences—start with something clear, concise and catchy that will spark your reader’s curiosity.

The hook should lead the reader into your essay, giving a sense of the topic you’re writing about and why it’s interesting. Avoid overly broad claims or plain statements of fact.

Examples: Writing a good hook

Take a look at these examples of weak hooks and learn how to improve them.

• Braille was an extremely important invention.
• The invention of Braille was a major turning point in the history of disability.

The first sentence is a dry fact; the second sentence is more interesting, making a bold claim about exactly  why the topic is important.

• The internet is defined as “a global computer network providing a variety of information and communication facilities.”
• The spread of the internet has had a world-changing effect, not least on the world of education.

Avoid using a dictionary definition as your hook, especially if it’s an obvious term that everyone knows. The improved example here is still broad, but it gives us a much clearer sense of what the essay will be about.

• Mary Shelley’s  Frankenstein is a famous book from the nineteenth century.
• Mary Shelley’s Frankenstein is often read as a crude cautionary tale about the dangers of scientific advancement.

Instead of just stating a fact that the reader already knows, the improved hook here tells us about the mainstream interpretation of the book, implying that this essay will offer a different interpretation.

Next, give your reader the context they need to understand your topic and argument. Depending on the subject of your essay, this might include:

• Historical, geographical, or social context
• An outline of the debate you’re addressing
• A summary of relevant theories or research about the topic
• Definitions of key terms

The information here should be broad but clearly focused and relevant to your argument. Don’t give too much detail—you can mention points that you will return to later, but save your evidence and interpretation for the main body of the essay.

How much space you need for background depends on your topic and the scope of your essay. In our Braille example, we take a few sentences to introduce the topic and sketch the social context that the essay will address:

Now it’s time to narrow your focus and show exactly what you want to say about the topic. This is your thesis statement —a sentence or two that sums up your overall argument.

This is the most important part of your introduction. A  good thesis isn’t just a statement of fact, but a claim that requires evidence and explanation.

The goal is to clearly convey your own position in a debate or your central point about a topic.

Particularly in longer essays, it’s helpful to end the introduction by signposting what will be covered in each part. Keep it concise and give your reader a clear sense of the direction your argument will take.

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

As you research and write, your argument might change focus or direction as you learn more.

For this reason, it’s often a good idea to wait until later in the writing process before you write the introduction paragraph—it can even be the very last thing you write.

When you’ve finished writing the essay body and conclusion , you should return to the introduction and check that it matches the content of the essay.

It’s especially important to make sure your thesis statement accurately represents what you do in the essay. If your argument has gone in a different direction than planned, tweak your thesis statement to match what you actually say.

To polish your writing, you can use something like a paraphrasing tool .

You can use the checklist below to make sure your introduction does everything it’s supposed to.

Checklist: Essay introduction

My first sentence is engaging and relevant.

I have introduced the topic with necessary background information.

I have defined any important terms.

My thesis statement clearly presents my main point or argument.

Everything in the introduction is relevant to the main body of the essay.

You have a strong introduction - now make sure the rest of your essay is just as good.

• Argumentative
• Literary analysis

This introduction to an argumentative essay sets up the debate about the internet and education, and then clearly states the position the essay will argue for.

The spread of the internet has had a world-changing effect, not least on the world of education. The use of the internet in academic contexts is on the rise, and its role in learning is hotly debated. For many teachers who did not grow up with this technology, its effects seem alarming and potentially harmful. This concern, while understandable, is misguided. The negatives of internet use are outweighed by its critical benefits for students and educators—as a uniquely comprehensive and accessible information source; a means of exposure to and engagement with different perspectives; and a highly flexible learning environment.

This introduction to a short expository essay leads into the topic (the invention of the printing press) and states the main point the essay will explain (the effect of this invention on European society).

In many ways, the invention of the printing press marked the end of the Middle Ages. The medieval period in Europe is often remembered as a time of intellectual and political stagnation. Prior to the Renaissance, the average person had very limited access to books and was unlikely to be literate. The invention of the printing press in the 15th century allowed for much less restricted circulation of information in Europe, paving the way for the Reformation.

This introduction to a literary analysis essay , about Mary Shelley’s Frankenstein , starts by describing a simplistic popular view of the story, and then states how the author will give a more complex analysis of the text’s literary devices.

Mary Shelley’s Frankenstein is often read as a crude cautionary tale. Arguably the first science fiction novel, its plot can be read as a warning about the dangers of scientific advancement unrestrained by ethical considerations. In this reading, and in popular culture representations of the character as a “mad scientist”, Victor Frankenstein represents the callous, arrogant ambition of modern science. However, far from providing a stable image of the character, Shelley uses shifting narrative perspectives to gradually transform our impression of Frankenstein, portraying him in an increasingly negative light as the novel goes on. While he initially appears to be a naive but sympathetic idealist, after the creature’s narrative Frankenstein begins to resemble—even in his own telling—the thoughtlessly cruel figure the creature represents him as.

Your essay introduction should include three main things, in this order:

• An opening hook to catch the reader’s attention.
• Relevant background information that the reader needs to know.
• A thesis statement that presents your main point or argument.

The length of each part depends on the length and complexity of your essay .

The “hook” is the first sentence of your essay introduction . It should lead the reader into your essay, giving a sense of why it’s interesting.

To write a good hook, avoid overly broad statements or long, dense sentences. Try to start with something clear, concise and catchy that will spark your reader’s curiosity.

A thesis statement is a sentence that sums up the central point of your paper or essay . Everything else you write should relate to this key idea.

The thesis statement is essential in any academic essay or research paper for two main reasons:

• It gives your writing direction and focus.
• It gives the reader a concise summary of your main point.

Without a clear thesis statement, an essay can end up rambling and unfocused, leaving your reader unsure of exactly what you want to say.

The structure of an essay is divided into an introduction that presents your topic and thesis statement , a body containing your in-depth analysis and arguments, and a conclusion wrapping up your ideas.

The structure of the body is flexible, but you should always spend some time thinking about how you can organize your essay to best serve your ideas.

How to Pick a College Essay Topic, According to an Admission Expert

The personal essay is one of the most crucial parts of a college application. While your transcripts and test scores highlight your achievement, they’re ultimately just stats and figures.

That’s where the college essay comes in: It helps colleges determine who you are. You can let your personality shine through and also show off your biggest wins — and explain away any potential shortcomings.

Of course, not everyone loves to write. And even if you do, it’s not always easy to figure out what to say. After all, most college essay prompts are quite vague. Where do you even start?

We spoke with Dan Phan, the academic program manager for USC Bovard Scholars , to learn how to pick the perfect college essay topic.

What Should a College Essay Focus On?

First things first: You need to determine what your dream school is asking for. Some will ask for just one essay, which is in response to several possible prompts. Usually, these prompts have to do with your background, your ambitions, challenging or formative times in your life or your personal beliefs. Other schools, however, will require you to write a personal statement, in addition to answering several shorter supplementary essay questions.

So, different universities have different application requirements. However, the essay’s goal remains the same, regardless of the prompt or format.

“The main personal statement should be introspective and shed light on the student’s core values, experiences that shaped them and aspirations for the future. Who is this student? Where have they been

Where do they hope to go?” Phan said.

What are Some Examples of College Essay Themes?

Many people use the college essay to reflect on hurdles in their lives. These difficulties could be related to academics or personal struggles. The idea is to show how you handle adversity. Essays can also focus on a personal turning point, to illustrate your personal growth or how you adapt to change.

Other applicants focus on topics related to identity and diversity, diving into their cultural background or family history to explore how their heritage and upbringing have shaped them into who they are today.

Some students write about their passions, hobbies or community involvement, showing what they have to offer besides good grades. It’s also a way to paint a picture of how they could participate in campus culture. After all, the goal is for the university to want you to be there and bring your personal touch to campus!

Phan’s favorite college essay themes?

“I love reading stories about the movers and shakers of the world, young adults that I can envision in the college setting, wherever that may be, and making a big difference once there,” she said.

And while Phan sees plenty of stories about family, culture, personal obstacles and achievements, she’s also read some “beautifully written essays” that she “remembers vividly to this day.”

The topics of these essays were wide-ranging and, often, highly personal.

“Playing music with symbrachydactyly (a hand anomaly characterized by missing fingers),” Phan recalled. “Visiting the neighborhood wig shop after school to chat with cancer patients. Defying gender stereotypes. Living close to the state prison and getting involved in prison-to-school pipeline programs. Car rides listening to NPR. Peach dumplings. Natural hair. Treasure maps.”

So, don’t be afraid to get creative. While your college essay should express who you are, there are many different ways to do so.

How Do You Choose a College Essay Topic?

When faced with vague prompts and open-ended suggestions, it can be hard to think of one story that summarizes who you are. Unfortunately, you can’t write about everything that makes you unique. Instead, narrow it down to a specific thesis.

Phan recommends that students think about the top four things a stranger would need to know to get acquainted with them.

“I encourage students to be vulnerable, to build connections and to think about some of their most formative or meaningful experiences, whether that involves family, identity, culture, extracurricular activities or interests,” Phan said.

Ask yourself what your strengths are. What are the skills and qualities that separate you from others? Then, consider the stories in your life that illustrate these traits.

Maybe you’re proud of your resilience. What’s a time in your life that it was tested? Or perhaps you have a passion for improving your community. What led you to that? What are some times you’ve demonstrated that dedication?

Once you consider what you want the essay to reveal about you, it’s easier to determine what examples in your life illustrate that.

“The most compelling essays are not only well written but have rich details that humanize the student’s experiences,” Phan said.

What Not to Write in Your College Essay

While you have plenty of options for your college essay, there are also some topics you don’t want to write about. For example, Phan advises applicants to avoid writing about grades or academic performance. Your transcript already covers that.

Another common pitfall? Not writing about yourself.

“Sometimes, students make the mistake of bringing in another person like a family member, friend or leader they admire, and the essay ceases to be about the student but rather about how incredible the other person is — which completely misses the point,” Phan explained.

Similarly, keep in mind that you’re writing about yourself now. That means you should be discussing who you are as a prospective college student, not who you were in kindergarten. While stories from your youth may help explain who you’ve become, the focus should always be on personal growth and development.

Some essay topics are so overused that they’ve become clichéd, such as teenage heartbreak, mission trip experiences or winning a sports game, Phan said: “Considering how admissions committees may be reading tens of thousands of applications each application cycle, admissions readers want to read unique college essays with fresh perspectives and angularity.”

Should Someone Proofread Your College Essay?

Applying for college is a process with many steps, and most students ask for help confirming they’ve done each part correctly. The same goes for your college essay!

Once you’ve selected the topic, it’s normal to ask for feedback to ensure you’re on the right track. Your college counselor or a teacher would be the right people to ask.

Similarly, it’s a good idea to ask them for help refining the essay once it’s done. They can help you deliver your thesis in the most compelling way possible. Remember, even the most talented writers need a copy editor to check that their work is free of misspellings and grammatical errors.

However, don’t have too many people read your essay.

“I’ve seen essays become so disjointed because there were too many voices in the essays,” Phan said. “Additionally, working with multiple people can pull students in different directions, resulting in a bit of Frankenstein of an essay and the student’s original voice being completely lost.”

So, trust your gut! With enough preparation, hard work and proofreading, you can write a solid college essay that makes you stand out to potential schools.
