A thesis statement summarizes the central points of your essay. It is a signpost telling the reader what the essay will argue and why.

The best thesis statements are:

• Concise: A good thesis statement is short and sweet—don’t use more words than necessary. State your point clearly and directly in one or two sentences.
• Contentious: Your thesis shouldn’t be a simple statement of fact that everyone already knows. A good thesis statement is a claim that requires further evidence or analysis to back it up.
• Coherent: Everything mentioned in your thesis statement must be supported and explained in the rest of your paper.

The thesis statement generally appears at the end of your essay introduction or research paper introduction .

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 and among young people more generally is hotly debated. For many 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 many benefits for education: the internet facilitates easier access to information, exposure to different perspectives, and a flexible learning environment for both students and teachers.

You should come up with an initial thesis, sometimes called a working thesis , early in the writing process . As soon as you’ve decided on your essay topic , you need to work out what you want to say about it—a clear thesis will give your essay direction and structure.

You might already have a question in your assignment, but if not, try to come up with your own. What would you like to find out or decide about your topic?

For example, you might ask:

After some initial research, you can formulate a tentative answer to this question. At this stage it can be simple, and it should guide the research process and writing process .

Prevent plagiarism. Run a free check.

Now you need to consider why this is your answer and how you will convince your reader to agree with you. As you read more about your topic and begin writing, your answer should get more detailed.

In your essay about the internet and education, the thesis states your position and sketches out the key arguments you’ll use to support it.

The negatives of internet use are outweighed by its many benefits for education because it facilitates easier access to information.

In your essay about braille, the thesis statement summarizes the key historical development that you’ll explain.

The invention of braille in the 19th century transformed the lives of blind people, allowing them to participate more actively in public life.

A strong thesis statement should tell the reader:

• Why you hold this position
• What they’ll learn from your essay
• The key points of your argument or narrative

The final thesis statement doesn’t just state your position, but summarizes your overall argument or the entire topic you’re going to explain. To strengthen a weak thesis statement, it can help to consider the broader context of your topic.

These examples are more specific and show that you’ll explore your topic in depth.

Your thesis statement should match the goals of your essay, which vary depending on the type of essay you’re writing:

• In an argumentative essay , your thesis statement should take a strong position. Your aim in the essay is to convince your reader of this thesis based on evidence and logical reasoning.
• In an expository essay , you’ll aim to explain the facts of a topic or process. Your thesis statement doesn’t have to include a strong opinion in this case, but it should clearly state the central point you want to make, and mention the key elements you’ll explain.

Follow these four steps to come up with a thesis statement :

• Ask a question about your topic .
• Write your initial answer.
• Develop your answer by including reasons.
• Refine your answer, adding more detail and nuance.

The thesis statement should be placed at the end of your essay introduction .

What Is a Thesis Statement?

Table of Contents

A thesis statement is a concise summary of the main point or claim of an essay, research paper, or other piece of academic writing.

It presents the topic of your paper and your position on the topic, ideally in a single sentence.

Think of it as the roadmap to your paper—it guides your readers through your arguments and provides a clear direction.

Key Elements of a Thesis Statement

• Clarity: Your thesis should be clear and specific.
• Position: It should convey your stance on the topic.
• Argument: The statement should make a claim that others might dispute.

Types of Thesis Statements

There are various types of thesis statements depending on the kind of paper you’re writing.

Here are the main ones:

• Standard Method – This is the classic thesis statement used in many academic essays. It provides a straightforward approach, clearly stating the main argument or claim and outlining the supporting points.
• Research Paper – Designed for research papers, this type involves extensive research and evidence. It presents a hypothesis or a central argument based on your research findings.
• Informative Essay – Used for essays that aim to inform or explain a topic. It provides a clear summary of what the reader will learn.
• Persuasive Essay – For essays meant to persuade or convince the reader of a particular point of view. It clearly states your position and outlines your main arguments.
• Compare and Contrast Essay – Used when comparing two or more subjects. It highlights the similarities and differences between the subjects and presents a clear argument based on these comparisons.
• Analytical Essay – Breaks down an issue or idea into its component parts, evaluates the issue or idea, and presents this breakdown and evaluation to the audience.

• Expository Essay – Explains or describes a topic in a straightforward, logical manner. It provides a balanced analysis of a subject based on facts without opinions.

How to write a thesis statement, what is a thesis statement.

Almost all of us—even if we don’t do it consciously—look early in an essay for a one- or two-sentence condensation of the argument or analysis that is to follow. We refer to that condensation as a thesis statement.

Why Should Your Essay Contain a Thesis Statement?

• to test your ideas by distilling them into a sentence or two
• to better organize and develop your argument
• to provide your reader with a “guide” to your argument

In general, your thesis statement will accomplish these goals if you think of the thesis as the answer to the question your paper explores.

How Can You Write a Good Thesis Statement?

Here are some helpful hints to get you started. You can either scroll down or select a link to a specific topic.

How to Generate a Thesis Statement if the Topic is Assigned How to Generate a Thesis Statement if the Topic is not Assigned How to Tell a Strong Thesis Statement from a Weak One

How to Generate a Thesis Statement if the Topic is Assigned

Almost all assignments, no matter how complicated, can be reduced to a single question. Your first step, then, is to distill the assignment into a specific question. For example, if your assignment is, “Write a report to the local school board explaining the potential benefits of using computers in a fourth-grade class,” turn the request into a question like, “What are the potential benefits of using computers in a fourth-grade class?” After you’ve chosen the question your essay will answer, compose one or two complete sentences answering that question.

Q: “What are the potential benefits of using computers in a fourth-grade class?” A: “The potential benefits of using computers in a fourth-grade class are . . .”

A: “Using computers in a fourth-grade class promises to improve . . .”

The answer to the question is the thesis statement for the essay.

[ Back to top ]

How to Generate a Thesis Statement if the Topic is not Assigned

Even if your assignment doesn’t ask a specific question, your thesis statement still needs to answer a question about the issue you’d like to explore. In this situation, your job is to figure out what question you’d like to write about.

A good thesis statement will usually include the following four attributes:

• take on a subject upon which reasonable people could disagree
• deal with a subject that can be adequately treated given the nature of the assignment
• express one main idea
• assert your conclusions about a subject

Let’s see how to generate a thesis statement for a social policy paper.

Brainstorm the topic . Let’s say that your class focuses upon the problems posed by changes in the dietary habits of Americans. You find that you are interested in the amount of sugar Americans consume.

You start out with a thesis statement like this:

Sugar consumption.

This fragment isn’t a thesis statement. Instead, it simply indicates a general subject. Furthermore, your reader doesn’t know what you want to say about sugar consumption.

Narrow the topic . Your readings about the topic, however, have led you to the conclusion that elementary school children are consuming far more sugar than is healthy.

You change your thesis to look like this:

Reducing sugar consumption by elementary school children.

This fragment not only announces your subject, but it focuses on one segment of the population: elementary school children. Furthermore, it raises a subject upon which reasonable people could disagree, because while most people might agree that children consume more sugar than they used to, not everyone would agree on what should be done or who should do it. You should note that this fragment is not a thesis statement because your reader doesn’t know your conclusions on the topic.

Take a position on the topic. After reflecting on the topic a little while longer, you decide that what you really want to say about this topic is that something should be done to reduce the amount of sugar these children consume.

You revise your thesis statement to look like this:

More attention should be paid to the food and beverage choices available to elementary school children.

This statement asserts your position, but the terms more attention and food and beverage choices are vague.

Use specific language . You decide to explain what you mean about food and beverage choices , so you write:

Experts estimate that half of elementary school children consume nine times the recommended daily allowance of sugar.

This statement is specific, but it isn’t a thesis. It merely reports a statistic instead of making an assertion.

Make an assertion based on clearly stated support. You finally revise your thesis statement one more time to look like this:

Because half of all American elementary school children consume nine times the recommended daily allowance of sugar, schools should be required to replace the beverages in soda machines with healthy alternatives.

Notice how the thesis answers the question, “What should be done to reduce sugar consumption by children, and who should do it?” When you started thinking about the paper, you may not have had a specific question in mind, but as you became more involved in the topic, your ideas became more specific. Your thesis changed to reflect your new insights.

How to Tell a Strong Thesis Statement from a Weak One

1. a strong thesis statement takes some sort of stand..

Remember that your thesis needs to show your conclusions about a subject. For example, if you are writing a paper for a class on fitness, you might be asked to choose a popular weight-loss product to evaluate. Here are two thesis statements:

There are some negative and positive aspects to the Banana Herb Tea Supplement.

This is a weak thesis statement. First, it fails to take a stand. Second, the phrase negative and positive aspects is vague.

Because Banana Herb Tea Supplement promotes rapid weight loss that results in the loss of muscle and lean body mass, it poses a potential danger to customers.

This is a strong thesis because it takes a stand, and because it's specific.

2. A strong thesis statement justifies discussion.

Your thesis should indicate the point of the discussion. If your assignment is to write a paper on kinship systems, using your own family as an example, you might come up with either of these two thesis statements:

My family is an extended family.

This is a weak thesis because it merely states an observation. Your reader won’t be able to tell the point of the statement, and will probably stop reading.

While most American families would view consanguineal marriage as a threat to the nuclear family structure, many Iranian families, like my own, believe that these marriages help reinforce kinship ties in an extended family.

This is a strong thesis because it shows how your experience contradicts a widely-accepted view. A good strategy for creating a strong thesis is to show that the topic is controversial. Readers will be interested in reading the rest of the essay to see how you support your point.

3. A strong thesis statement expresses one main idea.

Readers need to be able to see that your paper has one main point. If your thesis statement expresses more than one idea, then you might confuse your readers about the subject of your paper. For example:

Companies need to exploit the marketing potential of the Internet, and Web pages can provide both advertising and customer support.

This is a weak thesis statement because the reader can’t decide whether the paper is about marketing on the Internet or Web pages. To revise the thesis, the relationship between the two ideas needs to become more clear. One way to revise the thesis would be to write:

Because the Internet is filled with tremendous marketing potential, companies should exploit this potential by using Web pages that offer both advertising and customer support.

This is a strong thesis because it shows that the two ideas are related. Hint: a great many clear and engaging thesis statements contain words like because , since , so , although , unless , and however .

4. A strong thesis statement is specific.

A thesis statement should show exactly what your paper will be about, and will help you keep your paper to a manageable topic. For example, if you're writing a seven-to-ten page paper on hunger, you might say:

World hunger has many causes and effects.

This is a weak thesis statement for two major reasons. First, world hunger can’t be discussed thoroughly in seven to ten pages. Second, many causes and effects is vague. You should be able to identify specific causes and effects. A revised thesis might look like this:

Hunger persists in Glandelinia because jobs are scarce and farming in the infertile soil is rarely profitable.

This is a strong thesis statement because it narrows the subject to a more specific and manageable topic, and it also identifies the specific causes for the existence of hunger.

Developing a Thesis Statement

Many papers you write require developing a thesis statement. In this section you’ll learn what a thesis statement is and how to write one.

Keep in mind that not all papers require thesis statements . If in doubt, please consult your instructor for assistance.

What is a thesis statement?

A thesis statement . . .

• Makes an argumentative assertion about a topic; it states the conclusions that you have reached about your topic.
• Makes a promise to the reader about the scope, purpose, and direction of your paper.
• Is focused and specific enough to be “proven” within the boundaries of your paper.
• Is generally located near the end of the introduction ; sometimes, in a long paper, the thesis will be expressed in several sentences or in an entire paragraph.
• Identifies the relationships between the pieces of evidence that you are using to support your argument.

Not all papers require thesis statements! Ask your instructor if you’re in doubt whether you need one.

Identify a topic

Your topic is the subject about which you will write. Your assignment may suggest several ways of looking at a topic; or it may name a fairly general concept that you will explore or analyze in your paper.

Consider what your assignment asks you to do

Inform yourself about your topic, focus on one aspect of your topic, ask yourself whether your topic is worthy of your efforts, generate a topic from an assignment.

Below are some possible topics based on sample assignments.

Sample assignment 1

Analyze Spain’s neutrality in World War II.

Identified topic

Franco’s role in the diplomatic relationships between the Allies and the Axis

This topic avoids generalities such as “Spain” and “World War II,” addressing instead on Franco’s role (a specific aspect of “Spain”) and the diplomatic relations between the Allies and Axis (a specific aspect of World War II).

Sample assignment 2

Analyze one of Homer’s epic similes in the Iliad.

The relationship between the portrayal of warfare and the epic simile about Simoisius at 4.547-64.

This topic focuses on a single simile and relates it to a single aspect of the Iliad ( warfare being a major theme in that work).

Developing a Thesis Statement–Additional information

Your assignment may suggest several ways of looking at a topic, or it may name a fairly general concept that you will explore or analyze in your paper. You’ll want to read your assignment carefully, looking for key terms that you can use to focus your topic.

Sample assignment: Analyze Spain’s neutrality in World War II Key terms: analyze, Spain’s neutrality, World War II

After you’ve identified the key words in your topic, the next step is to read about them in several sources, or generate as much information as possible through an analysis of your topic. Obviously, the more material or knowledge you have, the more possibilities will be available for a strong argument. For the sample assignment above, you’ll want to look at books and articles on World War II in general, and Spain’s neutrality in particular.

As you consider your options, you must decide to focus on one aspect of your topic. This means that you cannot include everything you’ve learned about your topic, nor should you go off in several directions. If you end up covering too many different aspects of a topic, your paper will sprawl and be unconvincing in its argument, and it most likely will not fulfull the assignment requirements.

For the sample assignment above, both Spain’s neutrality and World War II are topics far too broad to explore in a paper. You may instead decide to focus on Franco’s role in the diplomatic relationships between the Allies and the Axis , which narrows down what aspects of Spain’s neutrality and World War II you want to discuss, as well as establishes a specific link between those two aspects.

Before you go too far, however, ask yourself whether your topic is worthy of your efforts. Try to avoid topics that already have too much written about them (i.e., “eating disorders and body image among adolescent women”) or that simply are not important (i.e. “why I like ice cream”). These topics may lead to a thesis that is either dry fact or a weird claim that cannot be supported. A good thesis falls somewhere between the two extremes. To arrive at this point, ask yourself what is new, interesting, contestable, or controversial about your topic.

As you work on your thesis, remember to keep the rest of your paper in mind at all times . Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Derive a main point from topic

Once you have a topic, you will have to decide what the main point of your paper will be. This point, the “controlling idea,” becomes the core of your argument (thesis statement) and it is the unifying idea to which you will relate all your sub-theses. You can then turn this “controlling idea” into a purpose statement about what you intend to do in your paper.

Look for patterns in your evidence

Compose a purpose statement.

Consult the examples below for suggestions on how to look for patterns in your evidence and construct a purpose statement.

• Franco first tried to negotiate with the Axis
• Franco turned to the Allies when he couldn’t get some concessions that he wanted from the Axis

Possible conclusion:

Spain’s neutrality in WWII occurred for an entirely personal reason: Franco’s desire to preserve his own (and Spain’s) power.

Purpose statement

This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.

• The simile compares Simoisius to a tree, which is a peaceful, natural image.
• The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.

At first, the simile seems to take the reader away from the world of warfare, but we end up back in that world by the end.

This paper will analyze the way the simile about Simoisius at 4.547-64 moves in and out of the world of warfare.

Derive purpose statement from topic

To find out what your “controlling idea” is, you have to examine and evaluate your evidence . As you consider your evidence, you may notice patterns emerging, data repeated in more than one source, or facts that favor one view more than another. These patterns or data may then lead you to some conclusions about your topic and suggest that you can successfully argue for one idea better than another.

For instance, you might find out that Franco first tried to negotiate with the Axis, but when he couldn’t get some concessions that he wanted from them, he turned to the Allies. As you read more about Franco’s decisions, you may conclude that Spain’s neutrality in WWII occurred for an entirely personal reason: his desire to preserve his own (and Spain’s) power. Based on this conclusion, you can then write a trial thesis statement to help you decide what material belongs in your paper.

Sometimes you won’t be able to find a focus or identify your “spin” or specific argument immediately. Like some writers, you might begin with a purpose statement just to get yourself going. A purpose statement is one or more sentences that announce your topic and indicate the structure of the paper but do not state the conclusions you have drawn . Thus, you might begin with something like this:

• This paper will look at modern language to see if it reflects male dominance or female oppression.
• I plan to analyze anger and derision in offensive language to see if they represent a challenge of society’s authority.

At some point, you can turn a purpose statement into a thesis statement. As you think and write about your topic, you can restrict, clarify, and refine your argument, crafting your thesis statement to reflect your thinking.

As you work on your thesis, remember to keep the rest of your paper in mind at all times. Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Compose a draft thesis statement

If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or “working” thesis statement.

Begin with a purpose statement that you will later turn into a thesis statement.

Assignment: Discuss the history of the Reform Party and explain its influence on the 1990 presidential and Congressional election.

Purpose Statement: This paper briefly sketches the history of the grassroots, conservative, Perot-led Reform Party and analyzes how it influenced the economic and social ideologies of the two mainstream parties.

Question-to-Assertion

If your assignment asks a specific question(s), turn the question(s) into an assertion and give reasons why it is true or reasons for your opinion.

Assignment : What do Aylmer and Rappaccini have to be proud of? Why aren’t they satisfied with these things? How does pride, as demonstrated in “The Birthmark” and “Rappaccini’s Daughter,” lead to unexpected problems?

Beginning thesis statement: Alymer and Rappaccinni are proud of their great knowledge; however, they are also very greedy and are driven to use their knowledge to alter some aspect of nature as a test of their ability. Evil results when they try to “play God.”

Write a sentence that summarizes the main idea of the essay you plan to write.

Main idea: The reason some toys succeed in the market is that they appeal to the consumers’ sense of the ridiculous and their basic desire to laugh at themselves.

Make a list of the ideas that you want to include; consider the ideas and try to group them.

• nature = peaceful
• war matériel = violent (competes with 1?)
• need for time and space to mourn the dead
• war is inescapable (competes with 3?)

Use a formula to arrive at a working thesis statement (you will revise this later).

• although most readers of _______ have argued that _______, closer examination shows that _______.
• _______ uses _______ and _____ to prove that ________.
• phenomenon x is a result of the combination of __________, __________, and _________.

What to keep in mind as you draft an initial thesis statement

Beginning statements obtained through the methods illustrated above can serve as a framework for planning or drafting your paper, but remember they’re not yet the specific, argumentative thesis you want for the final version of your paper. In fact, in its first stages, a thesis statement usually is ill-formed or rough and serves only as a planning tool.

As you write, you may discover evidence that does not fit your temporary or “working” thesis. Or you may reach deeper insights about your topic as you do more research, and you will find that your thesis statement has to be more complicated to match the evidence that you want to use.

You must be willing to reject or omit some evidence in order to keep your paper cohesive and your reader focused. Or you may have to revise your thesis to match the evidence and insights that you want to discuss. Read your draft carefully, noting the conclusions you have drawn and the major ideas which support or prove those conclusions. These will be the elements of your final thesis statement.

Sometimes you will not be able to identify these elements in your early drafts, but as you consider how your argument is developing and how your evidence supports your main idea, ask yourself, “ What is the main point that I want to prove/discuss? ” and “ How will I convince the reader that this is true? ” When you can answer these questions, then you can begin to refine the thesis statement.

Refine and polish the thesis statement

To get to your final thesis, you’ll need to refine your draft thesis so that it’s specific and arguable.

• Ask if your draft thesis addresses the assignment
• Question each part of your draft thesis
• Clarify vague phrases and assertions
• Investigate alternatives to your draft thesis

Consult the example below for suggestions on how to refine your draft thesis statement.

Sample Assignment

Choose an activity and define it as a symbol of American culture. Your essay should cause the reader to think critically about the society which produces and enjoys that activity.

• Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.

Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.

Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.

While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.

While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.

This statement is now specific and fulfills all parts of the assignment. This version, like any good thesis, is not self-evident; its points, 1-4, will have to be proven with evidence in the body of the paper. The numbers in this statement indicate the order in which the points will be presented. Depending on the length of the paper, there could be one paragraph for each numbered item or there could be blocks of paragraph for even pages for each one.

Complete the final thesis statement

The bottom line.

As you move through the process of crafting a thesis, you’ll need to remember four things:

• Context matters! Think about your course materials and lectures. Try to relate your thesis to the ideas your instructor is discussing.
• As you go through the process described in this section, always keep your assignment in mind . You will be more successful when your thesis (and paper) responds to the assignment than if it argues a semi-related idea.
• Your thesis statement should be precise, focused, and contestable ; it should predict the sub-theses or blocks of information that you will use to prove your argument.
• Make sure that you keep the rest of your paper in mind at all times. Change your thesis as your paper evolves, because you do not want your thesis to promise more than your paper actually delivers.

In the beginning, the thesis statement was a tool to help you sharpen your focus, limit material and establish the paper’s purpose. When your paper is finished, however, the thesis statement becomes a tool for your reader. It tells the reader what you have learned about your topic and what evidence led you to your conclusion. It keeps the reader on track–well able to understand and appreciate your argument.

How to write a thesis statement + examples

What is a thesis statement?

Is a thesis statement a question, how do you write a good thesis statement, how do i know if my thesis statement is good, examples of thesis statements, helpful resources on how to write a thesis statement, frequently asked questions about writing a thesis statement, related articles.

A thesis statement is the main argument of your paper or thesis.

The thesis statement is one of the most important elements of any piece of academic writing . It is a brief statement of your paper’s main argument. Essentially, you are stating what you will be writing about.

You can see your thesis statement as an answer to a question. While it also contains the question, it should really give an answer to the question with new information and not just restate or reiterate it.

Your thesis statement is part of your introduction. Learn more about how to write a good thesis introduction in our introduction guide .

A thesis statement is not a question. A statement must be arguable and provable through evidence and analysis. While your thesis might stem from a research question, it should be in the form of a statement.

Tip: A thesis statement is typically 1-2 sentences. For a longer project like a thesis, the statement may be several sentences or a paragraph.

A good thesis statement needs to do the following:

• Condense the main idea of your thesis into one or two sentences.
• Answer your project’s main research question.
• Clearly state your position in relation to the topic .
• Make an argument that requires support or evidence.

Once you have written down a thesis statement, check if it fulfills the following criteria:

• Your statement needs to be provable by evidence. As an argument, a thesis statement needs to be debatable.
• Your statement needs to be precise. Do not give away too much information in the thesis statement and do not load it with unnecessary information.
• Your statement cannot say that one solution is simply right or simply wrong as a matter of fact. You should draw upon verified facts to persuade the reader of your solution, but you cannot just declare something as right or wrong.

As previously mentioned, your thesis statement should answer a question.

If the question is:

What do you think the City of New York should do to reduce traffic congestion?

A good thesis statement restates the question and answers it:

In this paper, I will argue that the City of New York should focus on providing exclusive lanes for public transport and adaptive traffic signals to reduce traffic congestion by the year 2035.

Here is another example. If the question is:

How can we end poverty?

A good thesis statement should give more than one solution to the problem in question:

In this paper, I will argue that introducing universal basic income can help reduce poverty and positively impact the way we work.

• The Writing Center of the University of North Carolina has a list of questions to ask to see if your thesis is strong .

A thesis statement is part of the introduction of your paper. It is usually found in the first or second paragraph to let the reader know your research purpose from the beginning.

In general, a thesis statement should have one or two sentences. But the length really depends on the overall length of your project. Take a look at our guide about the length of thesis statements for more insight on this topic.

Here is a list of Thesis Statement Examples that will help you understand better how to write them.

Every good essay should include a thesis statement as part of its introduction, no matter the academic level. Of course, if you are a high school student you are not expected to have the same type of thesis as a PhD student.

Here is a great YouTube tutorial showing How To Write An Essay: Thesis Statements .

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

• tells the reader how you will interpret the significance of the subject matter under discussion.
• is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
• directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
• makes a claim that others might dispute.
• is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

• Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
• Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
• Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
• Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
• Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

• Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
• Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
• Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
• Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
• Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

• Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

• Do I answer the question? Yes!
• Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
• Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
• Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
• Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

Writing a Paper: Thesis Statements

Basics of thesis statements.

The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).

Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.

Being Specific

This thesis statement has no specific argument:

Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.

This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.

Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.

The new revision here is still concise, as well as specific and arguable.  We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors.  We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").

Making a Unique Argument

This thesis draft repeats the language of the writing prompt without making a unique argument:

Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.

You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.

Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).

Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.

Creating a Debate

This thesis statement includes only obvious fact or plot summary instead of argument:

Needs Improvement: Leadership is an important quality in nurse educators.

A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators.  The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.

Better: Roderick's (2009) theory of participatory leadership  is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.

Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.

Choosing the Right Words

This thesis statement uses large or scholarly-sounding words that have no real substance:

Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.

There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.

Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.

Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.

Leaving Room for Discussion

This thesis statement is not capable of development or advancement in the paper:

Needs Improvement: There are always alternatives to illegal drug use.

This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.

Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).

In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.

Thesis Mad Libs

If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.

• In this essay, I argue ____, using ______ to assert _____.
• While scholars have often argued ______, I argue______, because_______.
• Through an analysis of ______, I argue ______, which is important because_______.

Words to Avoid and to Embrace

When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.

Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

While Sandel argues that pursuing perfection through genetic engineering would decrease our sense of humility, he claims that the sense of solidarity we would lose is also important.

This thesis summarizes several points in Sandel’s argument, but it does not make a claim about how we should understand his argument. A reader who read Sandel’s argument would not also need to read an essay based on this descriptive thesis.  

Broad thesis (arguable, but difficult to support with evidence) 

Michael Sandel’s arguments about genetic engineering do not take into consideration all the relevant issues.

This is an arguable claim because it would be possible to argue against it by saying that Michael Sandel’s arguments do take all of the relevant issues into consideration. But the claim is too broad. Because the thesis does not specify which “issues” it is focused on—or why it matters if they are considered—readers won’t know what the rest of the essay will argue, and the writer won’t know what to focus on. If there is a particular issue that Sandel does not address, then a more specific version of the thesis would include that issue—hand an explanation of why it is important.  

Arguable thesis with analytical claim 

While Sandel argues persuasively that our instinct to “remake” (54) ourselves into something ever more perfect is a problem, his belief that we can always draw a line between what is medically necessary and what makes us simply “better than well” (51) is less convincing.

This is an arguable analytical claim. To argue for this claim, the essay writer will need to show how evidence from the article itself points to this interpretation. It’s also a reasonable scope for a thesis because it can be supported with evidence available in the text and is neither too broad nor too narrow.  

Arguable thesis with normative claim 

Given Sandel’s argument against genetic enhancement, we should not allow parents to decide on using Human Growth Hormone for their children.

This thesis tells us what we should do about a particular issue discussed in Sandel’s article, but it does not tell us how we should understand Sandel’s argument.  

Questions to ask about your thesis 

• Is the thesis truly arguable? Does it speak to a genuine dilemma in the source, or would most readers automatically agree with it?  
• Is the thesis too obvious? Again, would most or all readers agree with it without needing to see your argument?  
• Is the thesis complex enough to require a whole essay's worth of argument?  
• Is the thesis supportable with evidence from the text rather than with generalizations or outside research?  
• Would anyone want to read a paper in which this thesis was developed? That is, can you explain what this paper is adding to our understanding of a problem, question, or topic?

How to Write a Strong Thesis Statement

A thesis can be found in many places—a debate speech, a lawyer’s closing argument, even an advertisement. But the most common place for a thesis statement (and probably why you’re reading this article) is in an essay.

Whether you’re writing an argumentative paper, an informative essay, or a compare/contrast statement, you need a thesis. Without a thesis, your argument falls flat and your information is unfocused. Since a thesis is so important, it’s probably a good idea to look at some tips on how to put together a strong one.

Guide Overview

What is a “thesis statement” anyway.

• 2 categories of thesis statements: informative and persuasive
• 2 styles of thesis statements
• Formula for a strong argumentative thesis
• The qualities of a solid thesis statement (video)

You may have heard of something called a “thesis.” It’s what seniors commonly refer to as their final paper before graduation. That’s not what we’re talking about here. That type of thesis is a long, well-written paper that takes years to piece together.

Instead, we’re talking about a single sentence that ties together the main idea of any argument . In the context of student essays, it’s a statement that summarizes your topic and declares your position on it. This sentence can tell a reader whether your essay is something they want to read.

2 Categories of Thesis Statements: Informative and Persuasive

Just as there are different types of essays, there are different types of thesis statements. The thesis should match the essay.

For example, with an informative essay, you should compose an informative thesis (rather than argumentative). You want to declare your intentions in this essay and guide the reader to the conclusion that you reach.

To make a peanut butter and jelly sandwich, you must procure the ingredients, find a knife, and spread the condiments.

This thesis showed the reader the topic (a type of sandwich) and the direction the essay will take (describing how the sandwich is made).

Most other types of essays, whether compare/contrast, argumentative, or narrative, have thesis statements that take a position and argue it. In other words, unless your purpose is simply to inform, your thesis is considered persuasive. A persuasive thesis usually contains an opinion and the reason why your opinion is true.

Peanut butter and jelly sandwiches are the best type of sandwich because they are versatile, easy to make, and taste good.

In this persuasive thesis statement, you see that I state my opinion (the best type of sandwich), which means I have chosen a stance. Next, I explain that my opinion is correct with several key reasons. This persuasive type of thesis can be used in any essay that contains the writer’s opinion, including, as I mentioned above, compare/contrast essays, narrative essays, and so on.

2 Styles of Thesis Statements

Just as there are two different types of thesis statements (informative and persuasive), there are two basic styles you can use.

The first style uses a list of two or more points . This style of thesis is perfect for a brief essay that contains only two or three body paragraphs. This basic five-paragraph essay is typical of middle and high school assignments.

C.S. Lewis’s Chronicles of Narnia series is one of the richest works of the 20th century because it offers an escape from reality, teaches readers to have faith even when they don’t understand, and contains a host of vibrant characters.

In the above persuasive thesis, you can see my opinion about Narnia followed by three clear reasons. This thesis is perfect for setting up a tidy five-paragraph essay.

In college, five paragraph essays become few and far between as essay length gets longer. Can you imagine having only five paragraphs in a six-page paper? For a longer essay, you need a thesis statement that is more versatile. Instead of listing two or three distinct points, a thesis can list one overarching point that all body paragraphs tie into.

Good vs. evil is the main theme of Lewis’s Narnia series, as is made clear through the struggles the main characters face in each book.

In this thesis, I have made a claim about the theme in Narnia followed by my reasoning. The broader scope of this thesis allows me to write about each of the series’ seven novels. I am no longer limited in how many body paragraphs I can logically use.

Formula for a Strong Argumentative Thesis

One thing I find that is helpful for students is having a clear template. While students rarely end up with a thesis that follows this exact wording, the following template creates a good starting point:

___________ is true because of ___________, ___________, and ___________.

Conversely, the formula for a thesis with only one point might follow this template:

___________________ is true because of _____________________.

Students usually end up using different terminology than simply “because,” but having a template is always helpful to get the creative juices flowing.

The Qualities of a Solid Thesis Statement

When composing a thesis, you must consider not only the format, but other qualities like length, position in the essay, and how strong the argument is.

Length: A thesis statement can be short or long, depending on how many points it mentions. Typically, however, it is only one concise sentence. It does contain at least two clauses, usually an independent clause (the opinion) and a dependent clause (the reasons). You probably should aim for a single sentence that is at least two lines, or about 30 to 40 words long.

Position: A thesis statement always belongs at the beginning of an essay. This is because it is a sentence that tells the reader what the writer is going to discuss. Teachers will have different preferences for the precise location of the thesis, but a good rule of thumb is in the introduction paragraph, within the last two or three sentences.

Strength: Finally, for a persuasive thesis to be strong, it needs to be arguable. This means that the statement is not obvious, and it is not something that everyone agrees is true.

Example of weak thesis:

Peanut butter and jelly sandwiches are easy to make because it just takes three ingredients.

Most people would agree that PB&J is one of the easiest sandwiches in the American lunch repertoire.

Example of a stronger thesis:

Peanut butter and jelly sandwiches are fun to eat because they always slide around.

This is more arguable because there are plenty of folks who might think a PB&J is messy or slimy rather than fun.

Composing a thesis statement does take a bit more thought than many other parts of an essay. However, because a thesis statement can contain an entire argument in just a few words, it is worth taking the extra time to compose this sentence. It can direct your research and your argument so that your essay is tight, focused, and makes readers think.

How to Write a Strong Thesis Statement: 4 Steps + Examples

What’s Covered:

What is the purpose of a thesis statement, writing a good thesis statement: 4 steps, common pitfalls to avoid, where to get your essay edited for free.

When you set out to write an essay, there has to be some kind of point to it, right? Otherwise, your essay would just be a big jumble of word salad that makes absolutely no sense. An essay needs a central point that ties into everything else. That main point is called a thesis statement, and it’s the core of any essay or research paper.

You may hear about Master degree candidates writing a thesis, and that is an entire paper–not to be confused with the thesis statement, which is typically one sentence that contains your paper’s focus. 

Read on to learn more about thesis statements and how to write them. We’ve also included some solid examples for you to reference.

Typically the last sentence of your introductory paragraph, the thesis statement serves as the roadmap for your essay. When your reader gets to the thesis statement, they should have a clear outline of your main point, as well as the information you’ll be presenting in order to either prove or support your point. 

The thesis statement should not be confused for a topic sentence , which is the first sentence of every paragraph in your essay. If you need help writing topic sentences, numerous resources are available. Topic sentences should go along with your thesis statement, though.

Since the thesis statement is the most important sentence of your entire essay or paper, it’s imperative that you get this part right. Otherwise, your paper will not have a good flow and will seem disjointed. That’s why it’s vital not to rush through developing one. It’s a methodical process with steps that you need to follow in order to create the best thesis statement possible.

Step 1: Decide what kind of paper you’re writing

When you’re assigned an essay, there are several different types you may get. Argumentative essays are designed to get the reader to agree with you on a topic. Informative or expository essays present information to the reader. Analytical essays offer up a point and then expand on it by analyzing relevant information. Thesis statements can look and sound different based on the type of paper you’re writing. For example:

• Argumentative: The United States needs a viable third political party to decrease bipartisanship, increase options, and help reduce corruption in government.
• Informative: The Libertarian party has thrown off elections before by gaining enough support in states to get on the ballot and by taking away crucial votes from candidates.
• Analytical: An analysis of past presidential elections shows that while third party votes may have been the minority, they did affect the outcome of the elections in 2020, 2016, and beyond.

Step 2: Figure out what point you want to make

Once you know what type of paper you’re writing, you then need to figure out the point you want to make with your thesis statement, and subsequently, your paper. In other words, you need to decide to answer a question about something, such as:

• What impact did reality TV have on American society?
• How has the musical Hamilton affected perception of American history?
• Why do I want to major in [chosen major here]?

If you have an argumentative essay, then you will be writing about an opinion. To make it easier, you may want to choose an opinion that you feel passionate about so that you’re writing about something that interests you. For example, if you have an interest in preserving the environment, you may want to choose a topic that relates to that. 

If you’re writing your college essay and they ask why you want to attend that school, you may want to have a main point and back it up with information, something along the lines of:

“Attending Harvard University would benefit me both academically and professionally, as it would give me a strong knowledge base upon which to build my career, develop my network, and hopefully give me an advantage in my chosen field.”

Step 3: Determine what information you’ll use to back up your point

Once you have the point you want to make, you need to figure out how you plan to back it up throughout the rest of your essay. Without this information, it will be hard to either prove or argue the main point of your thesis statement. If you decide to write about the Hamilton example, you may decide to address any falsehoods that the writer put into the musical, such as:

“The musical Hamilton, while accurate in many ways, leaves out key parts of American history, presents a nationalist view of founding fathers, and downplays the racism of the times.”

Once you’ve written your initial working thesis statement, you’ll then need to get information to back that up. For example, the musical completely leaves out Benjamin Franklin, portrays the founding fathers in a nationalist way that is too complimentary, and shows Hamilton as a staunch abolitionist despite the fact that his family likely did own slaves. 

Step 4: Revise and refine your thesis statement before you start writing

Read through your thesis statement several times before you begin to compose your full essay. You need to make sure the statement is ironclad, since it is the foundation of the entire paper. Edit it or have a peer review it for you to make sure everything makes sense and that you feel like you can truly write a paper on the topic. Once you’ve done that, you can then begin writing your paper.

When writing a thesis statement, there are some common pitfalls you should avoid so that your paper can be as solid as possible. Make sure you always edit the thesis statement before you do anything else. You also want to ensure that the thesis statement is clear and concise. Don’t make your reader hunt for your point. Finally, put your thesis statement at the end of the first paragraph and have your introduction flow toward that statement. Your reader will expect to find your statement in its traditional spot.

If you’re having trouble getting started, or need some guidance on your essay, there are tools available that can help you. CollegeVine offers a free peer essay review tool where one of your peers can read through your essay and provide you with valuable feedback. Getting essay feedback from a peer can help you wow your instructor or college admissions officer with an impactful essay that effectively illustrates your point.

Using Thesis Statements

• Printable PDF Version
• Fair-Use Policy

When you are asked to write an essay that creates an argument, your reader will probably expect a clear statement of your position. Typically, this summary statement comes in the first paragraph of the essay, though there is no rigid rule about position. Here are some characteristics of good thesis statements, with samples of good and poor ones. Note that the better examples substitute specific argumentative points for sweeping general statements; they indicate a theoretical basis and promise substantial support. (See Some Myths About Thesis Statements, below, for a discussion of times not to use a thesis statement. See also the file General Advice on Essay Writing .)

1. It makes a definite and limited assertion that needs to be explained and supported by further discussion:

2. It shows the emphasis and indicates the methodology of your argument:

3. It shows awareness of difficulties and disagreements:

Some Myths about Thesis Statements

• Every paper requires one . Assignments that ask you to write personal responses or to explore a subject don’t want you to seem to pre-judge the issues. Essays of literary interpretation often want you to be aware of many effects rather than seeming to box yourself into one view of the text.
• A thesis statement must come at the end of the first paragraph. This is a natural position for a statement of focus, but it’s not the only one. Some theses can be stated in the opening sentences of an essay; others need a paragraph or two of introduction; others can’t be fully formulated until the end.
• A thesis statement must be one sentence in length, no matter how many clauses it contains . Clear writing is more important than rules like these. Use two or three sentences if you need them. A complex argument may require a whole tightly-knit paragraph to make its initial statement of position.
• You can’t start writing an essay until you have a perfect thesis statement . It may be advisable to draft a hypothesis or tentative thesis statement near the start of a big project, but changing and refining a thesis is a main task of thinking your way through your ideas as you write a paper. And some essay projects need to explore the question in depth without being locked in before they can provide even a tentative answer.
• A thesis statement must give three points of support . It should indicate that the essay will explain and give evidence for its assertion, but points don’t need to come in any specific number.

Thesis Statements

A thesis statement is a sentence (sometimes more than one sentence) in the introduction that tells the reader the following information:

• What the topic of the paper is
• How the writer intends to discuss that topic
•  It gives a blueprint for how the essay will be structured
•  How the writer intends to prove or demonstrate his or her main points.

Think of your paper as a human body, and your thesis statement as the spinal cord. Without it, there is no structure.

For you as the writer, the thesis statement:

Develops through the interrelationship of thinking, reading, and writing;

Limits your research by providing you with one controlling main idea that intrigues you;

Narrows your writing to one specific claim that you can develop or prove;

Organizes your ideas so you know the important points you want to make in your paper; and

Clarifies your writing by keeping you on target to fulfill your proposed purpose.

For your readers, the thesis statement:

 Identifies the main point and sub-points of your essay clearly and quickly;

Functions as a road map so your readers can easily follow your ideas; and

Gives satisfaction at the conclusion of the paper when your readers discover you have fulfilled your promise by proving or developing your main point.

Characteristics of Effective Thesis Statements

An effective thesis statement must be  factual and narrow.

An effective thesis statement prepares readers for facts and details, but it cannot itself be a fact. It must always be an inference that demands proof or further development. These proofs come from the literature. 

UNT Dallas campus has two buildings.

Not factual enough: The UNT Dallas campus is the perfect size.

Just Right:  While some might see small universities as a disadvantage, the small campus of UNT Dallas holds many advantages for students, including a close-knit campus community, smaller class sizes, and better support from professors.

2. Narrow Topic

A good thesis should be narrow, and not too broad or too vague. If the topic is too broad, you won’t be able to cover the entire topic in your paper.  If it’s too narrow, you might not be able to find research, and your paper probably won’t be long enough. 

Too Broad: College students have a lot of responsibilities.

Too Narrow: Student workers in the Learning Commons at UNT Dallas have many responsibilities in their course work and tutoring. 

Just Right: College students who are financially independent have many responsibilities as they must maintain good grades, pay living expenses, and balance work and school.

Remember, a thesis statement is not: 

• Instead , you should argue, based on facts and literature, why or why not NASA should receive more funding.  
• Ask yourself--can I find anything in literature to prove this point, or is this MY opinion? 
• Instead, you should argue why or why not people like chocolate OR why or why not chocolate is healthy for you based on facts and literature findings. 
• Similar to the subjective opinion, ask yourself is this statement is based on facts and literature findings or if this is YOUR opinion. Although it is ok to have your own opinion, professors usually do not like to read articles about beliefs (students have been writing about these for years and years). 
• Instead, you could discuss theories about politics or religions and use literature to prove or disprove those theories.
• This is too factual (the Himalayas WERE formed from a collision of tectonic plates), and there is nothing to discuss because this IS a fact in itself. 
• Instead, you could compare and contrast the tectonic plate formation of different mountains. 

Examples of Thesis Statements

A thesis statement f or a 5 paragraph essay conta ins three parts:.

1. A Topic: the main idea of the essay

2. The Controlling Idea: what you want to say about the topic

3. The subtopics: usually 3 examples/reasons you will discuss in your paper

Here is an example  of a thesis statement.

Ex: Regularly visiting the Writing Center at UNT Dallas will help you become the best writer on the planet because it offers superhero tutors, current technology, and fantastic handouts.

The main topic explores the idea that regularly vsiting the writing center will help you become the best writer on the planet, and the subtopics further expand this opinion with three distinct examples: 1) tutors, 2) technology, and 3) the handouts.

Outline Example

The paper should be organized around the subtopics.  For example, for the thesis written above, the writer would write one body paragraph about the tutors, one about technology, and one about the handouts. 

Here is a sample essay outline based on this thesis:

• Introduce the topic of tutoring
• Thesis (last sentence of intro): Regularly visiting the Writing Center at UNT Dallas will help you become the best writer on the planet because it offers superhero tutors, current technology, and fantastic handouts.
• topic sentence
• Restate thesis
• Concluding remarks

For further assistance with the structure, see our handouts on Introductions and Conclusions and Topic Sentences.

A thesis statement for a LONG ESSAY contains two parts: A Topic: the main idea of the essay The Controlling Idea: what you want to say about the topic 

Throughout the paper, your thesis promises your readers that you will prove specific facts or develop certain ideas ; therefore, every paragraph, sentence, and word in your paper must relate to this controlling idea.

Here are some examples of thesis statements.

• Baseball, once a national pastime and even an addiction, has lost its popularity because of the new interest in more violent sports.
• Since the space program has yet to provide the American people with any substantial, practical returns, it is a waste of money and should be dissolved.
• To stop the alarming rise in the number of violent crimes committed every year, our courts must hand out tougher sentences.
• Detective stories appeal to the basic human desire for thrills.
• Hemingway's war stories helped to create a new prose style.
• Bronte utilizes light and fire to symbolize the emotional expressions of the characters.

Here is a suggested outline for a long essay and how that would look in terms of your thesis statement, topic, and controlling ideas:

• Introduce the novel Jane Eyre and the topic of symbolism
• Thesis (last sentence of intro): Bronte utilizes light and fire to symbolize the emotional expressions of the characters.
• textual examples and elaboration

Developing Strong Thesis Statements

Welcome to the Purdue OWL

The thesis statement or main claim must be debatable

An argumentative or persuasive piece of writing must begin with a debatable thesis or claim. In other words, the thesis must be something that people could reasonably have differing opinions on. If your thesis is something that is generally agreed upon or accepted as fact then there is no reason to try to persuade people.

Example of a non-debatable thesis statement:

This thesis statement is not debatable. First, the word pollution implies that something is bad or negative in some way. Furthermore, all studies agree that pollution is a problem; they simply disagree on the impact it will have or the scope of the problem. No one could reasonably argue that pollution is unambiguously good.

Example of a debatable thesis statement:

This is an example of a debatable thesis because reasonable people could disagree with it. Some people might think that this is how we should spend the nation's money. Others might feel that we should be spending more money on education. Still others could argue that corporations, not the government, should be paying to limit pollution.

Another example of a debatable thesis statement:

In this example there is also room for disagreement between rational individuals. Some citizens might think focusing on recycling programs rather than private automobiles is the most effective strategy.

The thesis needs to be narrow

Although the scope of your paper might seem overwhelming at the start, generally the narrower the thesis the more effective your argument will be. Your thesis or claim must be supported by evidence. The broader your claim is, the more evidence you will need to convince readers that your position is right.

Example of a thesis that is too broad:

There are several reasons this statement is too broad to argue. First, what is included in the category "drugs"? Is the author talking about illegal drug use, recreational drug use (which might include alcohol and cigarettes), or all uses of medication in general? Second, in what ways are drugs detrimental? Is drug use causing deaths (and is the author equating deaths from overdoses and deaths from drug related violence)? Is drug use changing the moral climate or causing the economy to decline? Finally, what does the author mean by "society"? Is the author referring only to America or to the global population? Does the author make any distinction between the effects on children and adults? There are just too many questions that the claim leaves open. The author could not cover all of the topics listed above, yet the generality of the claim leaves all of these possibilities open to debate.

Example of a narrow or focused thesis:

In this example the topic of drugs has been narrowed down to illegal drugs and the detriment has been narrowed down to gang violence. This is a much more manageable topic.

We could narrow each debatable thesis from the previous examples in the following way:

Narrowed debatable thesis 1:

This thesis narrows the scope of the argument by specifying not just the amount of money used but also how the money could actually help to control pollution.

Narrowed debatable thesis 2:

This thesis narrows the scope of the argument by specifying not just what the focus of a national anti-pollution campaign should be but also why this is the appropriate focus.

Qualifiers such as " typically ," " generally ," " usually ," or " on average " also help to limit the scope of your claim by allowing for the almost inevitable exception to the rule.

Types of claims

Claims typically fall into one of four categories. Thinking about how you want to approach your topic, or, in other words, what type of claim you want to make, is one way to focus your thesis on one particular aspect of your broader topic.

Claims of fact or definition: These claims argue about what the definition of something is or whether something is a settled fact. Example:

Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:

Claims about value: These are claims made of what something is worth, whether we value it or not, how we would rate or categorize something. Example:

Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:

Which type of claim is right for your argument? Which type of thesis or claim you use for your argument will depend on your position and knowledge of the topic, your audience, and the context of your paper. You might want to think about where you imagine your audience to be on this topic and pinpoint where you think the biggest difference in viewpoints might be. Even if you start with one type of claim you probably will be using several within the paper. Regardless of the type of claim you choose to utilize it is key to identify the controversy or debate you are addressing and to define your position early on in the paper.

Thesis Statements

A thesis statement defines the scope and purpose of the paper. It needs to meet three criteria: 1. It must be arguable rather than a statement of fact. It should also say something original about the topic.     Bad thesis: Lily Bart experiences the constraints of many social conventions in The House of Mirth . [Of course she does. What does she do with these social conventions, and how does she respond to them? What's your argument about this idea?]     Better thesis: Lily Bart seeks to escape from the social conventions of her class in The House of Mirth , but her competing desires for a place in Selden's "republic of the spirit" and in the social world of New York cause her to gamble away her chances for a place in either world. [You could then mention the specific scenes that you will discuss.] 2. It must be limited enough so that the paper develops in some depth.     Bad thesis: Lily Bart and Clare Kendry are alike in some ways, but different in many others. [What ways?]     Better thesis: Lily Bart and Clare Kendry share a desire to "pass" in their respective social worlds, but their need to take risks and to reject those worlds leads to their destruction. 3. It must be unified so that the paper does not stray from the topic.     Bad thesis: Lily Bart gambles with her future, and Lawrence Selden is only a spectator rather than a hero of The House of Mirth . [Note: This is really the beginning of two different thesis statements.]     Better thesis: In The House of Mirth, Lawrence Selden is a spectator who prefers to watch and judge Lily than to help her. By failing to assist her on three separate occasions, he is revealed as less a hero of the novel than as the man responsible for Lily's downfall. [Note: Sometimes thesis statements are more than one sentence long.] 4. Statements such as "In this essay I will discuss " or "I will compare two stories in this paper" or "I was interested in Marji's relationship with God, so I thought I would talk about it in this essay" are not thesis statements and are unnecessary, since mentioning the stories in the introduction already tells the reader this. Topic Sentences Good topic sentences can improve an essay's readability and organization. They usually meet the following criteria: 1. First sentence. A topic sentence is usually the first sentence of the paragraph, not the last sentence of the previous paragraph. 2. Link to thesis . Topic sentences use keywords or phrases from the thesis to indicate which part of the thesis will be discussed. 3. Introduce the subject of the paragraph. They tell the reader what concept will be discussed and provide an introduction to the paragraph. 4. Link to the previous paragraph. They link the subject of the present paragraph to that of the previous paragraph. 5. Indicate the progression of the essay. Topic sentences may also signal to the reader where the essay has been and where it is headed through signposting words such as "first," "second," or "finally." Good topic sentences typically DON'T begin with the following. 1. A quotation from a critic or from the piece of fiction you're discussing. The topic sentence should relate to your points and tell the reader what the subject of the paragraph will be. Beginning the paragraph with someone else's words doesn't allow you to provide this information for the reader. 2. A piece of information that tells the reader something more about the plot of the story. When you're writing about a piece of literature, it's easy to fall into the habit of telling the plot of the story and then adding a sentence of analysis, but such an approach leaves the reader wondering what the point of the paragraph is supposed to be; it also doesn't leave you sufficient room to analyze the story fully. These "narrative" topic sentences don't provide enough information about your analysis and the points you're making.

Weak "narrative" topic sentence: Lily Bart next travels to Bellomont, where she meets Lawrence Selden again. Stronger "topic-based" topic sentence: A second example of Lily's gambling on her marriage chances occurs at Bellomont, where she ignores Percy Gryce in favor of Selden. [Note that this tells your reader that it's the second paragraph in a series of paragraph relating to the thesis, which in this case would be a thesis related to Lily's gambling on her marriage chances.]

3. A sentence that explains your response or reaction to the work, or that describes why you're talking about a particular part of it, rather than why the paragraph is important to your analysis. 

Weak "reaction" topic sentence: I felt that Lily should have known that Bertha Dorset was her enemy. Stronger "topic-based" topic sentence: Bertha Dorset is first established as Lily's antagonist in the train scene, when she interrupts Lily's conversation with Percy Gryce and reveals that Lily smokes.

The Thesis Sentence

The thesis sentence is arguably the most important sentence in an academic paper. Without a good, clear thesis that presents an intriguing arguable point, a paper risks becoming unfocused, aimless, not worth the reader's time.

The Challenge of the Thesis Sentence

Because the thesis sentence is the most important sentence of a paper, it is also the most difficult to write. Readers expect a great deal of a thesis sentence: they want it to powerfully and clearly indicate what the writer is going to say, why she is going to say it, and even how it is that she is going to go about getting it said. In other words, the job of the thesis sentence is to organize, predict, control, and define the paper's argument.

In many cases, a thesis sentence will not only present the paper's argument, it will also point to and direct the course that the argument is going to take. In other words, it may also include an "essay map" - i.e., phrases or clauses that map out for the reader (and the writer) the argument that is to come. In some cases, then, the thesis sentence not only promises an argument, it promises the structure of that argument as well.

The promises that a thesis sentence makes to a reader are important ones and must be kept. It's helpful sometimes to explain the thesis as a kind of contract between reader and writer: if this contract is broken, the reader will feel frustrated and betrayed. Accordingly, the writer must be very careful in the development of the thesis.

Working on the Thesis Sentence

Chances are if you've had trouble following or deciphering the argument of a paper, there's a problem with the thesis. If a tutor's first response to a paper is that he doesn't know what the paper is about, then the thesis sentence is either absent from the paper, or it's hiding. The first thing you might wish to do is to ask the writer what his thesis is. He may point to a particular sentence that he thinks is his thesis, giving you a very good place to start.

Let's say that you've read a paper in which you've encountered this thesis:

Although heterosexuality has long been regarded as the only natural expression of sexuality, this view has been recently and strongly challenged by the gay rights movement.

What's wrong with this sentence? Many things, the most troublesome of which is that it argues nothing. Who is going to deny that the heteronormative view has been challenged by the gay rights movement? At this point, you need to ask the writer some questions. In what specific ways has the gay rights movement challenged heterosexuality? Do these ways seem reasonable to the writer? Why or why not? What argument does he intend to make about this topic? Why does he want to make it? To whom does he want to make it?

After giving the writer some time to think about and talk about these questions, you'll probably want to bring up another problem that is certain to arise out of a thesis like this one: the matter of structure. Any paper that follows a thesis like this one is likely to ramble. How can the reader figure out what all the supporting paragraphs are doing when the argument itself is so ill-defined? You'll want to show the writer that a strong thesis suggests - even helps to create - strong topic sentences. (More on this when we consider matters of structure, below).

But before we move on to other matters, let's consider the problem of this thesis from another angle: its style. We can see without difficulty that the sentence presents us with at least two stylistic problems: 1) this thesis, which should be the most powerful sentence of the paper, employs the passive voice, and 2) the introductory clause functions as a dangling modifier (who regards heterosexuality as the only natural way to express sexuality?).

Both stylistic problems point to something at work in the sentence: the writer obliterates the actors - heterosexuals and homosexuals alike - by using the dangling modifier and the passive voice. Why does he do that? Is he avoiding naming the actors in these sentences because he's not comfortable with the positions they take? Is he unable to declare himself because he feels paralyzed by the sense that he must write a paper that is politically correct? Or does he obliterate the actors with the passive voice because he himself wishes to remain passive on this topic?

These are questions to pose to the writer, though they must be posed gently. In fact, you might gently pose these questions via a discussion of style. For instance, you might also suggest that the writer rewrite the sentence in the active voice:

Although our society has long regarded heterosexuality as the only natural expression of sexuality, members of the gay rights movement have challenged this view strongly.

This active construction helps us to see clearly what's missing:

Although our society has long regarded heterosexuality as the only natural expression of sexuality, members of the gay rights movement have challenged this view strongly, arguing XYZ.

This more active construction also makes it clear that merely enumerating the points the author wants to make is not the same thing as creating an argument. The writer should now be able to see that he needs to go one step further - he needs to reveal his own position on the gay rights movement. The rest of the paper will develop this position.

In short, there are many ways to begin work on a writer's thesis sentences. Almost all of them will lead you to other matters important to the paper's success: its structure, its language, its style. Try to make any conversation you have about thesis sentences point to other problems with the writing. Not only is this strategy efficient, but it also encourages a writer to see how important a thesis is to the overall success of his essay.

Talking Your Way to a Workable Thesis

For the sake of making (we hope) a somewhat humorous illustration of the matter at hand, we offer the following scenario, which shows how tutor and tutee can talk their way to a workable thesis - and, indeed, to a good essay. So sit back, and enjoy this "break" in your training.

Imagine (though it is indeed quite a stretch) that a freshman composition teacher has the audacity to assign a paper on cats (the animals, not the play). The students may write any kind of paper they like - narration, description, compare/contrast, etc. - as long as their essays contain a thesis (that is, that they argue some point) concerning cats. A writer comes to you for help in developing her thesis. You read the assignment, and then you tell the writer that she first must choose the kind of paper she would like to do. She decides to do a narrative because she thinks she has more freedom in the narrative form. Then you ask her what she has to say about cats. "I don't like them," is her reply.

"OK," you say, "that's a start. Why don't you like them?" The writer has lots of reasons: they smell, they're aloof, they shed, they keep you up nights when they're in heat, they're very middle class, they steal food off of the table, they don't get along with dogs (the writer loves dogs), and on, and on. After brainstorming for a while, you tell the writer to choose a few points on which she'd like to focus - preferably those points that she feels strongly about or those which seem unusual. She picks three: cats smell, they steal food, and they are middle class. She offers her thesis: "I don't like cats because they are smelly, thieving, and middle class."

"O.K.," you say, "It's not a very sophisticated thesis but we can use it for now. After all, it defines your stance, it controls your subject, it organizes your argument, and it predicts your strategy - all the things that a thesis ought to do. Now let's consider how to develop the thesis, point by point."

You begin to ask questions about cats and their smell. "What do they smell like?" you say. The writer thinks awhile, and then says, "They smell like dirty gym shorts, like old hamburgers, like my eighth-grade math teacher's breath." The writer laughs, particularly fond of the final simile. Then she adds, "My boyfriend has a cat. A Tom. When he moved into his first apartment, that cat sprayed all over the place, you know, marking his territory. The place stunk so bad that I couldn't even go there for a week. Can you imagine? Your boyfriend gets his first apartment, and you can't even go in the place for a week?"

The writer has sparked your imagination; you think that she can spark her teacher's imagination as well. "Why don't you do your narrative about your boyfriend's cat? You could tell the story - or you could make up a story - about going over there for dinner, hoping for a romantic evening, and being put off by the cat." The writer likes this idea and goes off to write her draft. She returns with the following story about her boyfriend and his cat.

She was hoping for a romantic dinner; he was making her favorite meal. She could smell the T-bone and the apple pie before she even got to his door. But when she opened the door, her appetite was obliterated: the smell of cat spray smelled worse than her eighth-grade math teacher's breath. Of course, because she remained hopeful for a romantic evening, she put on her best face, tried not to grimace, and gave her boyfriend the flowers she'd picked up on the way. They chat; everything is going fine; he goes to the kitchen to check on dinner; she hears his shriek. The cat has stolen all of the food! Upon searching, they find the cat under the sofa, not only with their dinner, but with the writer's wallet, her favorite picture of her mom torn in half, her new leather jacket now full of cat hairs. This cat not only stinks, he's a thief as well. Still, the evening need not be a total waste. They order pizza, have some wine. She and her man talk; their moods improve, and she decides that it might be a nice time to kiss. She pulls the old yawn trick to get her arm around him, and just as she's ready to kiss him the cat jumps into his lap. "Oh, Pookie, Pookie, Pookie," her boyfriend says, giving himself over to the purring cat. "Damn lap cat," the writer says to herself, and leaves it at that. She has written a paper illustrating that cats are smelly, thieving, and middle class. She has fulfilled her thesis.

Now, you like this paper. It's got a great voice, and it's got humor. You feel, however, that the writer should refine the thesis. It has served the writer well in helping her to organize, control, predict, and define her essay; however, she needs now to consider how to choose words and a tone which will hook the reader and reel him in. You explain to the writer that her thesis can be humorous, that she can feel free to be extreme, because a funny, exaggerated thesis would suit this funny, exaggerated paper.

After some doodling and some dialogue, the writer comes up with the following thesis: "All cats should be exterminated because they are the stinking, kleptomaniacal darlings of the bourgeoisie." You laugh; you like it. Moreover, the thesis has given the writer an ending for her essay: she exterminates the cat in her boyfriend's microwave, convinces him to get a goldfish instead, and the two of them live happily ever after. The writer is happy. The tutor is happy. The paper works.

While you will likely not encounter a "cat" assignment at Dartmouth, this sort of experience with writing a thesis is a common one. Even when papers are more sophisticated than this one - even when the subject is Hitler's rise to power, or Freud's treatment of taboo - writers will often write a working thesis, one that guides them through the writing process. Then they will return to the thesis, sometimes several times before their paper is finished, revising it to better fit their paper's increasingly refined argument and tone.

Polishing the Thesis Sentence

Look at the sentence's structure. Is the main idea of the paper placed appropriately in the main clause? If there are parallel points made in the paper, does the thesis sentence signal this to the reader via some parallel structure? If the paper makes an interesting but necessary aside, is that aside predicted - perhaps in a parenthetical element? Remember: the structure of the thesis sentence also signals much to the reader about the structure of the argument. Be sure that the thesis reflects, reliably, what the paper itself is going to say.

As to the style of the sentence: hold the thesis sentence to the highest stylistic standards. Help a writer to make sure that it is as clear and concise as it can be, and that its language and phrasing reflect confidence, eloquence, and grace.
