This post is written by guest writer Dixie-Ann Belle. You can learn more about Dixie-Anne at the end of this article. Welcome Dixie-Ann! 

You might not realize it, but chances are this is not your first encounter with this type of essay. Once you have been writing essays in academic environments, you have probably already worked on expository writing.

In this article, I hope to help you recognize this essay type and understand the expository essay outline. Comprehending the building blocks is instrumental in knowing how to construct an exceptional expository essay.

Lay a Strong Foundation

Over the years, I have taught and tutored college students one on one as they write academic essays, in face to face classrooms and online, and I have noticed a pattern. They often approach essays in one of two ways.

Some consider them with apprehension and are fearful of making mistakes. Others feel confident that they have written many essays before and think they have already mastered expository writing.

Interestingly, it's the latter who often end up the most shaken when they realize that they are not as familiar as they think with this type of writing.

What I hope to instill in my students is that they should not feel intimidated whatever their situation or essay assignment.

I encourage them to make sure they understand the foundations of the expository essay structure. I try to get them to grasp the basic blocks that need to be there, and once they do, they have a good chance of crafting a substantial piece of writing.

What is an Expository Essay?

Students are typically assigned one of at least four types of essays: the persuasive/argumentative essay, the descriptive essay, the technical essay, or the expository essay.

Writing an expository essay is one of the most important and valuable skills for you to master.

According to the Purdue Online Writing Lab:

The expository essay is a genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner.

Keep in mind that your expository writing centers on giving your reader information about a given topic or process. Your goal is to inform, describe, or define the subject for your readers.

As you work to achieve this, your essay writing must be formal, objective, and concise. No matter what your discipline, it's almost guaranteed that you will be required to write this common type essay one day.

Some expository essay examples could include:

  • Define the term ‘democracy'
  • Compare and contrast the benefits of cable television vs streaming
  • Outline the process that generates an earthquake
  • Classify the different types of tourism
  • Outline the aspects of a good fitness program

The possibilities are endless with expository writing, and it can cover a wide variety of topics and specialties.

3 Building Blocks of a Great Expository Essay

To make sure you're on the right track with this type of paper, it helps to understand the three building blocks of the expository essay format and how to apply them to the final expository essay structure .

1. Write an introduction

Most students know that an introductory paragraph should grab the interest of the reader. However, they might not realize that it should also provide context for the essay topic.

Ask yourself : What are you talking about in this essay? Why is this topic important? Some background details could help to establish the subject for your reader.

For example:

If you were writing an essay on the impact smartphones have on society, you might want to start with some information on the evolution of smartphones, the number of smartphones in society, the way people use the phones and more.

The introduction should start off with general information.

You then work your way down to the more specific and principal part of your introduction and the crown of your whole essay, the thesis statement.

What is the thesis statement?

Your thesis statement states in concise language what this essay is going to be about. It is one clear sentence which expresses the subject and the focus of this piece of writing. If there is a prompt, the thesis statement should directly answer that prompt.

Our smart phones topic might create a thesis statement like:  Smart phones have many positive impacts for adults in the business world.

Right away the reader has some idea of what's ahead.

2. Write your body paragraphs

With your thesis statement clear in your mind and your introduction setting the scene, it is time to write your body paragraphs.

Each body paragraph contains supporting information including factual evidence for your essay topic. Each paragraph should each focus on one idea.

Depending on your word count and the teacher requirements, you can write any number of body paragraphs, but there are usually at least three for a basic five paragraph essay.

Each body paragraph should start with a topic sentence. A topic sentence is one single statement that explains the point of the paragraph. It directly refers to your thesis statement and tells you what the body paragraph is going to be about.

Remember our smart phone thesis statement? You need something that will relate to that thesis sentence and will alert the reader to what is to come.

Here's one possibility: 

Smart phones can help increase productivity  for professional adults.

This topic sentence not only reminds us that you are talking about positive impacts for adults with smart phones, it now shows us what the following paragraph will cover.

The best body paragraphs will go on to include different types of details, all of which would support your topic sentence. A good abbreviation to encapsulate the different details is spelt TEEES.

The TEEES Body Paragraph Structure

Let's break down this abbreviation and explore the types of details you'll need in your body paragraphs

T: Topic sentence

You'll begin with your topic sentence establishing the purpose of this paragraph. We'll use our example from above:

Smartphones can help increase productivity for professional adults.

E: Explanation

This is where you expand on your topic and include additional supportive information.

If you were talking about smartphones and productivity, maybe you could mention what elements of the smartphone make it optimal for productivity.

E: Evidence

This is the information from reputable sources you researched for your topic. Here's where you can talk about all the information you have discovered from experts who have carefully studied this subject.

For our smartphone essay, perhaps you could mention a quote from a technology reporter who has been following the rise of smartphones for years.

E: Examples

This would be concrete subject matter to support your point.

Maybe here you can list some of the smartphone apps which have proven to increase productivity in the workplace.

S: Significant/Summarizing sentence

This is the last sentence in the body paragraph which summarizes your point and ends this part of your essay. There should be no doubt in the reader's mind that you have finished talking about your topic, and you are moving on to another in the next paragraph. Here's how we could conclude this paragraph on smartphones and productivity:

Smartphones have transformed the productivity of the modern workforce.

3. Write the conclusion

Once you have written your body paragraphs, you're in the home stretch. You have presented all of your points and supported them with the appropriate subject matter. Now you need to conclude.

A lot of students are confused by conclusions. Many of them have heard different rules about what is supposed to be included.

One of the main requirements to keep in mind when ending an expository essay is that you do not add new information.

This is not the time to throw in something you forgot in a previous body paragraph. Your conclusion is supposed to give a succinct recap of the points that came before.

Sometimes college students are instructed to re-state the thesis, and this puzzles them. It doesn't mean re-writing the thesis statement word for word. You should express your thesis statement in a new way.

For example, here's how you could approach the conclusion for our smartphone essay.

You've come up with three points to support your thesis statement, and you've explored these three points in your body paragraphs. After brainstorming, you might decide the benefits of smartphones in the workplace are improved productivity, better communication, and increased mobility.

Your conclusion is the time to remind your reader of these points with concise language. Your reader should be able to read the conclusion alone and still come away with the basic ideas of your essay.

Plan Your Essay Based on an Expository Essay Outline

While writing fiction, it is sometimes okay to “pants” it and just leap into writing your story.

When writing essays in academia, this is rarely a good idea. Planning your essay helps organize your ideas, helps you refine many of your points early on and saves time in the long run.

There are lots of great brainstorming techniques you can use to get your ideas together, but after that, it's time to create a topic to sentence outline.

There are three steps to creating your topic to sentence essay outline.

  • Develop a powerful thesis statement. Remember, this is the overarching idea of your entire essay, so you have completed a significant step once you have one done.
  • Come up with the ideas you would like to support your thesis statement.
  • Based on your points, craft your topic sentences.

Here is an example of a topic to sentence outline:

Having these important foundation details completed is a great way to develop your essay as you build on each part. It is also an effective method to make sure you are on the right track.

Depending on your instructor (or tutor, if you have one), you can show your outline to them to get feedback before you launch into your entire essay.

Even if you don't have anyone to provide a critique, the outline can make it easier to revise how you will approach the rest of your paragraph essay.

You now have some firm foundations to help you as you construct your expository essay.

How do you organize an expository essay?  Let us know in the comments .

Take fifteen minutes to practice writing your own expository essay.

First, choose an expository writing assignment topic. If you can't think of one, use one of the expository essay examples below .  

  • What are the nutritional elements of a healthy breakfast?
  • What are some of the most influential types of music?
  • Compare and contrast the benefits of electric and gas cars. 
  • What are the major steps to planning a stress-free vacation?
  • How do smartphones affect mental health?
  • Define true love.

Craft a thesis statement about your topic. Then, write three topic sentences for your body paragraphs.

With the time you have left, start writing your essay. You might be surprised how much you can write in fifteen minutes when you have a clear outline for your essay!

When your time is up, share your outline and your essay in the Pro Practice Workshop here . After you post, please be sure to give feedback to your fellow writers.

How to Write an Expository Essay

4-minute read

  • 29th March 2020

An expository essay explains something. This means investigating an idea, looking at evidence, coming to a conclusion, and explaining your thinking. But how do you write a strong expository essay? Our top tips include:

  • Read the essay prompt carefully and using it to guide your research.
  • Come up with a thesis statement (i.e., a position that you’ll explain).
  • Plan the structure of your essay before you start writing.
  • Once you have a first draft, revise and proofread to make sure it is perfect.

For more advice on how this works, check out the guide below.

1. Read Your Essay Prompt

Most expository essay prompts will ask you to do one of the following:

  • Define and explain a concept or theory.
  • Compare and contrast two ideas.
  • Examine a problem and propose a solution.
  • Describe a cause and effect relationship.
  • Explain a step-by-step process.
  • Analyze a broad subject and classify examples into groups.

When you’ve been set an expository assignment, then, check the prompt or question carefully. You can use the phrasing to guide your research. You may also need to select a topic to write about. If so, try to think of something:

  • You already know at least something about.
  • You find interesting enough to research.
  • That fits with the instructions in the essay prompt (e.g., if you’ve been asked to contrast two things, you’ll need a topic that allows for a comparison).
  • That is narrow enough to discuss in one essay.

Start by brainstorming topics, then narrow it down to one or two ideas.

2. Come Up with a Thesis Statement

Once you have a topic, you’ll need to do some research and develop a thesis statement. This is the proposition or position that you’ll explain in your essay.

Your thesis statement should be something you can back up with evidence and facts, as well as something that answers the question in your essay prompt. Keep in mind, too, that an expository essay should present a balanced account of the facts available, not personal opinions. For instance, we’ve come up with thesis statements for a few example essay prompts:

When you’ve selected a thesis, make sure you’ve got evidence to back it up! This may mean doing a little more research before you start writing.

3. Structuring an Expository Essay

The exact length and content of your essay will depend on the topic and prompt. However, most expository essays follow a similar basic structure:

  • Introduction – A paragraph where you introduce the essay topic and your thesis statement (i.e., the issue or idea you will explain in the essay).
  • Main Body – A series of short paragraphs in which you explain your thesis statement, providing evidence and arguments to support each point.
  • Conclusion – A final paragraph where you restate your thesis and how your evidence supports this. Try not to introduce any new information here (if it’s important, it should go in the main body).
  • References – If required, include a bibliography of sources you’ve used.

Before you start writing, then, create an essay outline with the structure above in mind and plan what each paragraph will say.

4. Editing and Proofreading

When you have a first draft, take a break and re-read it. Now comes the redrafting ! This is where you go back over your essay and look for areas to improve. Do you provide enough evidence? Is your argument clear? Even a few tweaks may increase your mark, so make sure to redraft at least once!

Finally, make sure to have your essay proofread before you submit it for marking. This will ensure your writing is error free and easy to read, giving you an even better chance of getting the grades you deserve.

How to Write an Expository Essay Better, Faster, and In a More Satisfying Manner

What Is an Expository Essay?

If you find yourself here, it's likely because you've recently received an assignment for an expository essay, or perhaps you're drawn to exploring ideas beyond the surface level. Whatever the reason, we're here to guide you through the expository essay definition, its outline, and examples.

Let's start by understanding what an expository essay is and its purpose. In simple terms, an expository essay provides information on a particular topic, elucidating aspects of a situation, person, idea, or event and conveying knowledge to the reader. Unlike persuasive writing, it doesn't seek to sway the audience's opinion but relies on facts to inform and educate about the subject. 

From sharing personal experiences to outlining work assignments, expository writing covers a broad spectrum of questions, making it arguably the most prevalent form of writing worldwide. If at any point you feel overburdened with assignments, use our essay writing services to relax and wrap up your homework faster.

in what part of an expository essay does the author present the main idea

Why Students Have to Write Expository Essays?

Expository writing serves a distinct purpose – to impart knowledge to the reader. While it may offer entertainment or persuasion as secondary benefits, these are not the primary objectives of the author. A well-crafted piece of expository writing showcases the author's expertise on the subject and often reveals their journey of acquiring knowledge.

For instance, consider the task of crafting an essay about a mock trial your class conducted. In an expository essay, you would begin by introducing the assignment and detailing the case your class tackled during the trial. Subsequent body sections would systematically elaborate on each stage of the mock trial process – covering discovery, opening statements, cross-examination, closing statements, jury deliberation, and the final verdict – illustrating how your class navigated through each phase. Concluding the essay, you would present the verdict reached by your class and the judge's ruling.

Crucially, your expository essay on the mock trial does not take a stance on whether the ruling was right or wrong. Instead, it elucidates the procedural intricacies your class followed, offering a comprehensive understanding of how real court cases progress through the legal system. In essence, your essay is a presentation of facts and processes rather than expressing personal opinion or commentary.

Types of Expository Essays

As previously noted, expository essays manifest in various forms. These encompass the following types:

Classification 

In the realm of classification essays, you delve into various subjects within a single category, examining the distinctive characteristics of each subject while highlighting the traits that connect them to others in the same category. For instance, a classification essay on herding dogs could commence with a thesis statement elucidating the differences between herding breeds from other dog categories. Subsequent paragraphs would then delve into specific herding breeds, such as corgis, collies, heelers, and more.

A definition essay elucidates its subject by presenting factual data. To illustrate, your definition essay might challenge prevalent myths surrounding a historical event by offering firsthand accounts from primary sources. It would also delve into relevant social, political, and economic trends that influenced the event, shaping perceptions of it. We’d also like to recommend you read our guide on how to write a descriptive essay .

A process essay guides the reviewer through the steps required to complete a task akin to a recipe. The opening passage of a process essay outlines the covered process and the anticipated result. Each body chapter corresponds to a step in the process, leading to a conclusion that explains what the reader should have accomplished by following each step.

Compare and Contrast

In a compare-and-contrast essay, your key statement is substantiated by examining the differences and similarities between cited sources. For instance, an essay comparing and contrasting school dress codes might scrutinize variations in allowed clothing items and the precision of language in each policy. It could also explore the degree of ambiguity present in the rules of each dress code.

Cause and Effect 

True to its name, a cause-and-effect essay delves into how specific events or actions trigger subsequent occurrences. These essays often trace chains of events to comprehend the reasons behind current circumstances. An example could be a cause-and-effect essay tracking the influence of shifting market trends on regional industries over the past few decades, ultimately shaping the present local economy. Our guide on writing a narrative essay could also help increase your knowledge and skills.

Expository Essay Structure

Structuring an expository essay follows the familiar format applicable to any essay assignment: an introduction, a main body for elaboration and support, and a concluding section that reinforces your thesis and restates key points. While there's no strict word count requirement unless specified by your instructor, your essay should comprehensively express your ideas, maintaining a logical and accurate flow. Adhering to the following format, with the flexibility to adjust the number of sections based on supporting points, will effectively guide your expository essay:

Expository essay outline

Introduction

In this opening section, you introduce your essay topic, present your thesis statement, and aim to engage the reader with captivating facts. Providing the necessary context and introducing supporting evidence help your audience grasp the essence of your focal sentence.

First Body Paragraph

Dedicate a separate passage for each supporting point you make. While the traditional five-paragraph structure is often considered standard, you may require more subsections to convey your thesis statement thoroughly.

Second Body Paragraph

Write smooth transitions between verses using appropriate transition words and sentences. These transitional elements convey the relationships between subparagraphs, clarifying the purpose of each point and its contribution to your overall argument.

Third Body Paragraph

As you approach the final writing clause, focus on transitioning to your conclusion. Avoid premature summarization; instead, offer insightful details comparable to your earlier items.

In the concluding section, restate your thesis statement and succinctly recap the key points covered in your body. Ensure a cohesive closure, addressing any remaining questions your professor might have and tying up loose ends neatly.

Expository Essay Writing Tips

While you now have a solid understanding of the expository essay format, there are additional considerations to bear in mind. This section will guide you through specific steps to take when tackling the task of writing an expository essay.

How to write an expository essay

Do Your Research

Start by thoroughly reviewing the assignment guidelines to ensure a clear understanding of requirements, including potential topic restrictions and word counts. Consider writing down different concepts aligned with the types of expository essays and gauge which type best suits your chosen theme. Reflect on class discussions, teacher expectations, and personal interests to generate a list of potential questions. Conduct preliminary research on each topic to evaluate the availability of reputable sources and deepen your understanding, leading to a well-informed and engaging expository essay subject.

Create an Outline

Once you've selected a topic, initiate research with a focus on developing body paragraphs, considering three main ways to explain the topic. While researching, contemplate potential thesis statements, allowing them to evolve organically with the accumulation of evidence. Develop an expository essay outline, organizing information under the relevant chapters to streamline the writing process. Writing a preliminary thesis statement by the end of the planning stage provides a clear direction for your research and writing.

Prepare the First Draft

Now is the time to translate your outline into full sentences. It is often useful to leave the introduction till the end because after writing the central paragraphs, you will have a better idea of what to say in an introduction, but make sure that you write down your thesis statement. Use the information you have found to create a cohesive analysis of the topic in each paragraph. Make sure that the information you present is on point and connects to the other facts around it. Think about what the purpose of each body section is and question whether the info you are presenting fits that purpose or not. Make sure to use transition words within the paragraph and transition sentences between paragraphs to improve overall comprehensibility and flow.

Finish the Draft

Go over the first draft of the expository essay and focus on whether the different paragraphs make sense or not. Don't be afraid of writing sections over or completely getting rid of some pieces of information. As you write your draft, new ways of expressing the testimony that will make the overall text more powerful can come to mind. Make sure that you are not trying to make a persuasive argument and that you are using facts rather than opinions as evidence. 

Check each sentence to make sure that it is clear and that it fits the purpose of the paragraph it is in. Look at the details you have included and ensure they are useful and enhance your understanding of the topic. It is better to have less information than more if the supporting data is distracting or does not add anything to the expository essay. Try to read the paper as if it is the first time you are coming across the subject matter to see if it makes sense or not. Congratulations, you are just one step away from writing and submitting an A-grade expository paper!

Revise the Document

As the writing stage is over, scan through the final draft of your expository essay to check for formatting errors, grammatical errors, spelling mistakes, etc., and make sure that it complies with all the guidelines of the assignment. Finally, ask a friend or relative to go over the paper to do the last check. If you feel like you still need to make a lot of changes, don't be disheartened, spend the extra time to consult our persuasive essay guide for more insights.

What is an expository essay?

The expository essay is a genre of essay that requires the student to investigate an idea, evaluate evidence, expound on the idea, and set forth an argument concerning that idea in a clear and concise manner. This can be accomplished through comparison and contrast, definition, example, the analysis of cause and effect, etc.

Please note : This genre is commonly assigned as a tool for classroom evaluation and is often found in various exam formats.

The structure of the expository essay is held together by the following.

  • A clear, concise, and defined thesis statement that occurs in the first paragraph of the essay.

It is essential that this thesis statement be appropriately narrowed to follow the guidelines set forth in the assignment. If the student does not master this portion of the essay, it will be quite difficult to compose an effective or persuasive essay.

  • Clear and logical transitions between the introduction, body, and conclusion.

Transitions are the mortar that holds the foundation of the essay together. Without logical progression of thought, the reader is unable to follow the essay’s argument, and the structure will collapse.

  • Body paragraphs that include evidential support.

Each paragraph should be limited to the exposition of one general idea. This will allow for clarity and direction throughout the essay. What is more, such conciseness creates an ease of readability for one’s audience. It is important to note that each paragraph in the body of the essay must have some logical connection to the thesis statement in the opening paragraph.

  • Evidential support (whether factual, logical, statistical, or anecdotal).

Often times, students are required to write expository essays with little or no preparation; therefore, such essays do not typically allow for a great deal of statistical or factual evidence.

  • A bit of creativity!

Though creativity and artfulness are not always associated with essay writing, it is an art form nonetheless. Try not to get stuck on the formulaic nature of expository writing at the expense of writing something interesting. Remember, though you may not be crafting the next great novel, you are attempting to leave a lasting impression on the people evaluating your essay.

  • A conclusion that does not simply restate the thesis, but readdresses it in light of the evidence provided.

It is at this point of the essay that students will inevitably begin to struggle. This is the portion of the essay that will leave the most immediate impression on the mind of the reader. Therefore, it must be effective and logical. Do not introduce any new information into the conclusion; rather, synthesize and come to a conclusion concerning the information presented in the body of the essay.

A complete argument

Perhaps it is helpful to think of an essay in terms of a conversation or debate with a classmate. If I were to discuss the cause of the Great Depression and its current effect on those who lived through the tumultuous time, there would be a beginning, middle, and end to the conversation. In fact, if I were to end the exposition in the middle of my second point, questions would arise concerning the current effects on those who lived through the Depression. Therefore, the expository essay must be complete, and logically so, leaving no doubt as to its intent or argument.

The five-paragraph Essay

A common method for writing an expository essay is the five-paragraph approach. This is, however, by no means the only formula for writing such essays. If it sounds straightforward, that is because it is; in fact, the method consists of:

  • an introductory paragraph
  • three evidentiary body paragraphs
  • a conclusion

Writing an expository essay? Start strong with Paperpal’s Templates. Create the perfect outline in minutes!  

The primary goal of expository writing is to explain or clarify a concept, process, or phenomenon using evidence, examples, and logical reasoning. Unlike persuasive or argumentative essays, the purpose of an expository essay is not to convince the reader of a particular viewpoint or opinion, but rather to provide clear and concise information.

The main objectives of expository writing are:

  • Informing: Expository writing aims to educate and provide readers with new or valuable information. It seeks to convey facts, details, concepts, or ideas about a topic in a straightforward and concise manner.
  • Explaining: Expository writing helps readers grasp complex subjects by breaking them down into simpler terms. It aims to clarify abstract concepts, processes, or phenomena, making them more accessible and understandable.
  • Instructing: Expository writing provides step-by-step instructions or guidelines on how to perform a task, accomplish a goal, or understand a process. It offers a clear sequence of actions or explanations to ensure readers can follow and replicate the instructions.
  • Presenting an analysis: Expository writing often involves analyzing and evaluating information, data, or evidence related to a particular subject. It may include comparing and contrasting different viewpoints, examining cause-and-effect relationships, or offering an objective evaluation of a situation.

Overall, the purpose of expository writing is to provide readers with accurate, unbiased, and well-organized information about a specific topic. It aims to enhance understanding, broaden knowledge, and facilitate learning by presenting information in a clear, coherent, and logical manner.

An expository essay is a good choice when the goal is to inform, explain, describe, or instruct. You may be assigned an expository essay as part of an in-class exam or coursework assignment. Here are some common situations in which writing an expository essay would be appropriate:

  • Academic Assignments: Expository essays are frequently assigned in educational settings. Teachers often use this type of essay to assess students’ understanding of a particular subject or to teach them how to research and present information effectively. They are common in subjects such as English, history, science, social studies, or any discipline that requires a clear explanation or analysis of a topic.
  • Instructional or How-to Writing: When you want to provide step-by-step instructions or guidance on how to perform a task, solve a problem, or achieve a specific outcome, an expository essay can be an appropriate format. This type of writing is commonly used in manuals, guidebooks, tutorials, or any instructional material.
  • Journalism or News Writing: Expository writing is prevalent in journalism, where the goal is to inform readers about current events, news stories, or investigative reports. Journalists strive to present objective information, provide background details, and explain complex issues clearly to their audience.
  • Professional or Technical Writing: In various professional fields, such as business, healthcare, engineering, or law, expository writing is utilized to convey information to colleagues, clients, or the general public. This includes writing reports, memos, manuals, research papers, or any form of communication that requires clear and factual presentation of information.

Expository essays can serve different purposes and present information in various ways. Here are five common types of expository essays:

  • Descriptive essay: This type of expository essay focuses on describing a person, place, object, event, or any subject in detail. It aims to create a vivid and sensory-rich portrayal of the topic, using language that appeals to the reader’s senses and emotions.
  • Process essay: Also known as a “how-to” essay, a process essay explains a sequence of steps or procedures to accomplish a task or achieve a particular outcome. It provides clear instructions and guidance, breaking down complex processes into manageable and easy-to-follow stages.
  • Compare-and-contrast essay: This type of expository essay explores the similarities and differences between two or more subjects. It involves examining various aspects, characteristics, or elements of the subjects and highlighting their similarities, differences, or both.
  • Cause-and-effect essay: A cause-and-effect essay explores the reasons (causes) behind an event, situation, or phenomenon, as well as the consequences (effects) that result from it. It aims to analyze and explain the relationship between causes and effects, demonstrating how one factor leads to another.
  • Problem-and-solution essay: In this type of expository essay, a specific problem or issue is identified and analyzed, followed by the presentation of potential solutions or strategies to address it. The essay outlines the problem, examines its causes and effects, and proposes practical solutions or recommendations.

It’s important to note that these are not the only types of expository essays, and there can be variations or combinations of these types. Additionally, within each type, the specific approach and structure can vary depending on the requirements of the assignment or the writer’s purpose.

Structuring an expository essay involves organizing your thoughts, ideas, and information in a clear and logical manner. Here is a commonly used structure for an expository essay:

  • Begin with an attention-grabbing hook to engage the reader.
  • Provide some background information on the topic to set the context.
  • Present a clear and concise thesis statement that states the main idea or purpose of the essay.
  • Start each paragraph with a clear topic sentence that introduces the main point of the paragraph.
  • Support your topic sentence with evidence, facts, examples, or expert opinions that relate to the main point.
  • Provide detailed explanations, analysis, or descriptions to clarify and develop your ideas.
  • Use transitional words and phrases to ensure smooth flow and coherence between paragraphs and ideas.
  • Each paragraph should focus on a specific aspect or subtopic related to the main idea.
  • Restate the thesis statement but rephrase it in a way that reinforces the main idea.
  • Summarize the main points discussed in the body paragraphs.
  • Avoid introducing new information or ideas in the conclusion.
  • End with a closing statement that leaves a lasting impression.

You should consider writing an expository essay when you need to explain, inform, or describe a particular topic or subject to your readers. Expository essays are usually assigned in academic settings, but they can also be used in other contexts, such as writing articles or blog posts. For example, an expository essay would be appropriate for purposes such as explaining the benefits of a healthy lifestyle, describing the process of a scientific experiment, or discussing the impact of technology on society.

Expository essay: The main purpose of an expository essay is to explain, describe, or inform the reader about a particular topic or subject. It should be written in a neutral manner, focusing on presenting facts, explaining concepts, and offering a clear understanding of the topic. Argumentative essay: The primary purpose of an argumentative essay is to present a well-structured argument or position on a specific issue. The writer takes a clear stance on a topic and provides strong arguments, counterarguments, and evidence to support their position. The language used may be more passionate and persuasive to convince the reader.

The length of an expository essay can vary depending on the specific requirements or guidelines provided by your instructor or the purpose of your writing. Expository essays can range from a few hundred words for shorter essays to several thousand words for more in-depth or research-based essays. The number of body paragraphs typically range from three to five, but it can vary based on the complexity of the topic and the amount of information you need to convey.

Learning Objectives

  • Understand the function and use of expository essays
  • Identify eight types of expository essays
  • Apply expository essay structure

What Is an Expository Essay?

An essay that explains a writer’s ideas by defining, explaining, informing, or elaborating on points to allow the reader to clearly understand the concept.

Many of your future academic workplace writing assignments will be expository–explaining your ideas or the significance of a concept or action. An expository essay allows the writer the opportunity to explain his or her ideas about a topic and to provide clarity for the reader by using:

  • Explanations
  • Definitions

It may also include the writer outlining steps of a procedure in a way that is straightforward for the reader to follow. It is purely informative and often contains elements of summary.

Imagine you need to verbally explain a concept to your classmates, maybe a behavioural theory. What are the key elements on which you would focus? How would you organize the information? You could explain who came up with the theory, the specific area of study to which it is related, its purpose, and the significant details to explain the theory. Telling these four elements to your classmates would give them a complete, yet summarized, picture of the theory, so they could apply the theory in future discussions.

Although you did this verbally, you were still fulfilling the elements of an expository essay by providing definition, details, explanations, and maybe even facts if you have a really good memory. This is the same process that you would use when you write an expository essay. You may actually be doing this all the time; for example, when you are giving someone directions to a place or explaining how to cook something. In the following sections of the chapter, you will practise doing this more in different expository written forms.

The Structure of an Expository Essay

Sections versus paragraphs.

Before looking at the general structure of an expository essay, you first need to know that in your post-secondary education, you should not consider your essay as writing being constructed with five paragraphs as you might have been used to in high school. You should instead think of your essay in terms of sections (there may be five), and each section may have multiple paragraphs.

To understand further why you need to think beyond the five-paragraph essay, imagine you have been asked to submit a six-page paper (approximately 1,500 words). You already know that each paragraph should be roughly 75 to 200 words long. If you divide the required word count by five paragraphs (1,500 by 5), you end with 300 words per paragraph, way above the number you should have in a paragraph. If your paragraphs are too long, they likely have too many ideas and your reader may become confused. Your paragraphs should be two-third of a page at most, and never longer than a page.

Instead, if you think of your essays being divided into sections (with possibly more than one paragraph per section), your writing will likely be more organized and allow your reader to follow your presentation of ideas without creating too much distance between your paragraph’s supporting points and its topic sentence.

As you will see in Section 4.5, some essay forms may require even more than five paragraphs or sections because of how many points are necessary to address. For the rest of this chapter, the term paragraph will also imply section.

Sections of an Expository Essay

An expository essay, regardless of its purpose, should have at least five sections, which are:

  • Introduction
  • First body section/paragraph
  • Second body section/paragraph
  • Third body section/paragraph
  • Conclusion.

The introduction should state the topic of your paper: your thesis statement as well as brief signposts of what information the rest of the paper will include. That is, you only want to mention the content of the body paragraphs; you do not want to go in to a lot of detail and repeat what will be in the rest of the essay.

The first body section or paragraph should focus on one of your main points and provide evidence to support that point. There should be two to three supporting points: reasons, facts, statistics, quotations, examples, or a mix of these. Both the second and third body sections should follow the same pattern. Providing three body sections with one point each that supports the thesis should provide the reader with enough detail to be convinced of your argument or fully understand the concept you are explaining. However, remember that some sections will require more explanation, and you may need to separate this information into multiple paragraphs.

You can order your sections in the most logical way to explain your ideas. For example, if you are describing a process, you may use chronological order to show the definite time order in which the steps need to happen. You will learn about the different ways to organize your body paragraphs in the next chapter.

The concluding paragraph , or conclusion, can be a little tricky to compose because you need to make sure you give a concise summary of the body paragraphs, but you must be careful not to simply repeat what you have already written. Look back at the main idea of each section/paragraph, and try to summarize the point using words different from those you have already used. Do not include any new points in your concluding paragraph.

Consider Your Audience: How Much Do They Know?

Later in this chapter, you will work on determining and adapting to your audience when writing, but with an expository essay, since you are defining or informing your audience on a certain topic, you need to evaluate how much your audience knows about that topic (aside from having general common knowledge). You want to make sure you are giving thorough, comprehensive, and clear explanations on the topic. Never assume the reader knows everything about your topic (even if it is covered in the reader’s field of study). For example, even though some of your instructors may teach criminology, they may have specialized in different areas from the one about which you are writing; they most likely have a strong understanding of the concepts but may not recall all the small details on the topic. If your instructor specialized in crime mapping and data analysis for example, he or she may not have a strong recollection of specific criminological theories related to other areas of study. Providing enough background information without being too detailed is a fine balance, but you always want to ensure you have no gaps in the information, so your reader will not have to guess your intention. Again, we will practise this more in Section 4.9.

What Comes Next?

In the next eight sections (4.2 through 4.9), we will look at different expository modes, or rhetorical modes, you will often be assigned. These are:

  • Illustration
  • Description
  • Classification
  • Process analysis
  • Compare and contrast
  • Cause and effect

Rhetorical modes refers simply to the ways to communicate effectively through language. As you read about these modes, keep in mind that the rhetorical mode a writer chooses depends on his or her purpose for writing. Sometimes writers incorporate a variety of modes in any one essay. In this chapter, we also emphasize the rhetorical modes as a set of tools that will allow you greater flexibility and effectiveness in communicating with your audience and expressing your ideas.

In a few weeks, you will need to submit your first essay–an expository sample–and you will be given the choice of topic: one from each of the modes. Think about which types of expository essays are easier and which are more challenging for you. As mentioned, as you progress through your studies, you will be exposed to each of these types. You may want to explore a mode you find more challenging than the others in order to ensure you have a full grasp on developing each type. However, it is up to you. As you work through the sections, think about possible topics you may like to cover in your expository essay and start brainstorming as you work through the self-practice exercises.

After we explore each of the individual modes in the eight sections that follow, we will look at outlining and drafting; it is at this point you will want to fine tune and narrow the topic you will write about, so you can focus on that when doing the exercises.

Expository essays are often assigned in academic settings. In an expository essay, you need to consider an idea, investigate the idea, then explain the idea. Some expository essays may include an argument, while others are purely informative. [1] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source While it may seem overwhelming, writing an expository essay is easy if you take it one step at a time.

Sample Essay Conclusion

in what part of an expository essay does the author present the main idea

Planning Your Essay

Step 1 Define your purpose for writing.

  • If you are writing an expository essay for an assignment, read the assignment guidelines. Ask your instructor if anything seems unclear.

Step 2 Consider your audience.

  • If you are writing your essay for a class assignment, consider what your instructor will expect you to include in your essay.

Step 3 Generate ideas for your expository essay.

  • Try listing. List all your ideas for your expository essay. Then look over the list you have made and group similar ideas together. Expand those lists by adding more ideas or by using another prewriting activity. [6] X Research source
  • Try freewriting. Write nonstop for about 10 minutes. Write whatever comes to mind and don’t edit yourself. After you finish writing, review what you have written. Highlight or underline the most useful information for your expository essay. Repeat the freewriting exercise using the passages you underlined as a starting point. You can repeat this exercise many times to continue to refine and develop your ideas. [7] X Research source
  • Try clustering. Write a brief explanation of the subject of your expository essay on the center of a piece of paper and circle it. Then draw three or more lines extending from the circle. Write a corresponding idea at the end of each of these lines. Continue developing your cluster until you have explored as many connections as you can. [8] X Research source
  • Try questioning. On a piece of paper, write out “Who? What? When? Where? Why? How?” Space the questions about two or three lines apart on the paper so that you can write your answers on these lines. Respond to each question in as much detail as you can. [9] X Research source

Step 4 Make an outline.

  • Trustworthy internet sources usually include academic institutions like universities or research labs, government websites, and non-profit organizations.

Step 6 Evaluate your sources to determine their credibility before you decide to use them.

  • Identify the author and his or her credentials. Think about what qualifies this person to write about their subject. If the source has no author or the author does not have adequate credentials, then this source may not be trustworthy.
  • Check for citations to see if this author has researched the topic well enough. If the author has provided few or no sources, then this source may not be trustworthy.
  • Look for bias. Think about whether or not this author has presented an objective, well-reasoned account of the topic. If the author seems to value a particular argument or slant that is not supported or only thinly supported by fact, then this source may not be trustworthy.
  • Consider the publication date to see if this source presents the most up to date information on the subject.
  • Cross-check some of the information in the source. If you are still concerned about a source, cross-check some of its information against a trustworthy source.

Step 7 Read your sources well.

  • Show when you have quoted a source word for word by putting it into quotation marks. Include information about the source such as the author’s name, article title or book title, and page number.
  • Write down the publishing information of each source. You will need this information for your "References," "Bibliography," or "Works Cited" pages. Format this page according to your instructor's guidelines.

Step 9 Develop your tentative thesis.

  • Make sure your thesis is arguable. Do not state facts or matters of taste. For example, "George Washington was the first president of the United States," is not a good thesis because it states a fact. Likewise, "Die Hard is a great movie," is not a good thesis because it expresses a matter of taste. [16] X Trustworthy Source University of North Carolina Writing Center UNC's on-campus and online instructional service that provides assistance to students, faculty, and others during the writing process Go to source
  • Make sure your thesis provides enough detail. In other words, avoid just saying that something is "good" or "effective." Instead, say what makes something "good" or "effective. [17] X Trustworthy Source University of North Carolina Writing Center UNC's on-campus and online instructional service that provides assistance to students, faculty, and others during the writing process Go to source

Introducing Your Essay

Step 1 Begin with an engaging sentence that gets right into your topic.

  • An engaging hook can take many forms. You could start with an anecdote, an informative and attention-grabbing quote, a bold opinion statement, or anything that will make your readers want to continue with your essay.

Step 2 Provide context.

  • If you are writing about a book, provide the name of the work, the author, and a brief summary of the plot.
  • If you are writing about a specific day in history, summarize the day's events. Then, explain how it fits into a broader historical scope.
  • If you are writing about a person, name the person and provide a brief biography.
  • Keep in mind that your context should lead up to your thesis statement. Explain everything your reader needs to know to understand what your topic is about. Then narrow it down until you reach the topic itself.

Step 3 Provide your thesis statement.

Expressing Your Main Points

Step 1 Determine how many paragraphs to include.

  • A five-paragraph essay should include three body paragraphs. Each body paragraph should discuss a piece of supporting evidence that supports your thesis.
  • Even if your essay is longer than five paragraphs, the same principles still apply. Each paragraph should discuss a piece of supporting evidence.

Step 2 Begin each paragraph with a topic sentence.

  • "Dogs played an active role in Marine Corps missions in the Pacific."
  • "The Doberman Pinscher was the official dog of the US Marine Corps during WWII, but all breeds were eligible to train as war dogs."
  • "War dogs were even eligible to receive military awards for their service."

Step 3 Elaborate on your supporting evidence.

  • Most of your evidence should be in the form of cited quotes, paraphrases, and summaries from your research.
  • Your evidence could also come from interviews, anecdotes, or personal experience.
  • Try to provide at least two to three pieces of evidence to support each of your claims.
  • For example, if a paragraph starts with, "War dogs were even eligible to receive military awards for their service," the supporting evidence might be a list of dogs who got awards and the awards they were given.

Step 4 Analyze the significance of each piece of evidence.

  • You could write, "Even though Dobermans were the most common breed used in WWII, they were not the only breed, and were not the only dogs recognized for their help."

Concluding Your Essay

Step 1 Restate and rephrase your thesis.

  • Note that the second sentence repeats the information provided in your original thesis. It just says it in a new way while also hinting at the information you included in the body of the essay.

Step 2 Summarize and review your main ideas.

  • Explain how the topic affects the reader
  • Explain how your narrow topic applies to a broader theme or observation
  • Call the reader to action or further exploration on the topic
  • Present new questions that your essay introduced

About This Article

Tristen Bonacci

Before you write an expository essay, take some time to jot down ideas for your essay. Try the clustering method by writing a brief explanation of your subject in a bubble in the center of your page. Then, draw 3 or more lines extending from the circle and jot down idea bubbles that connect to your main theme. Once you have a plan for your expository essay, write out an outline to organize what you’re going to say. Make sure to begin your outline with an engaging introduction sentence. After the introduction sentence, provide some background information and include your thesis statement, which is your main argument. If you’re writing a 5 paragraph essay, you should include 3 body paragraphs after your introduction then a conclusion paragraph that summarizes your main points. However you organize your essay, make sure to include credible sources for important information, like statistics, so your teacher knows that it’s accurate.

What is an Expository Essay?

An expository essay is a type of essay that seeks to inform, describe, or explain a particular subject or topic. 

It's distinct in its approach as it emphasizes presenting facts, analyzing information, and providing a comprehensive understanding without incorporating personal opinions or biases.

Why Write an Expository Essay?

The purpose of writing an expository essay extends beyond academic requirements. 

This form of writing nurtures the ability to research deeply, logically organize thoughts, and articulate information coherently. 

Developing these skills not only enhances academic performance but also prepares individuals for effectively communicating complex ideas in various real-world scenarios.

Expository Essay Vs. Argumentative Essay

Expository and argumentative essays vary in their purposes and approaches. 

Expository essays aim to inform or describe a topic without personal opinions, using a neutral, informative tone. 

On the other hand, argumentative essays seek to persuade by presenting a clear viewpoint and supporting it with evidence. 

Expository essays follow a simpler structure, providing information, while argumentative essays involve complex structures, presenting and countering arguments. Understanding these differences helps in choosing the right essay type for specific writing goals.

Types of Expository Essay

Before we dive into the different types of expository essays, let's check out five common ones:

Descriptive Essays

Descriptive essays aim to create a detailed image or sensory experience in the reader's mind by vividly describing a particular place, object, person, or event. 

They use rich language and sensory details to paint a clear picture and evoke emotions, making the reader feel like they're experiencing what's being described.

Process Analysis Essays

In a process analysis essay , the writer breaks down a series of steps needed to achieve a specific task or goal. 

They provide a clear, step-by-step guide, making complex tasks easy to understand. For example, they might explain how to bake a cake, fix a bicycle, or perform a scientific experiment.

Compare and Contrast Essays

Compare and contrast essays focus on exploring the similarities and differences between two or more subjects. 

They present a balanced view, showing how things are alike and how they're different. Whether it's comparing different cultures, products, historical events, or ideas, these essays aim to offer insights into relationships and contrasts.

Cause and Effect Essays

Cause and effect essays delve into examining the causes that lead to specific effects or the effects that arise from certain causes. 

They analyze the relationship between events, explaining why things happen and what outcomes result from those actions or occurrences. They aim to provide a clear understanding of the connections between different elements.

Problem and Solution Essays

Focused on a specific issue, problem and solution essays identify a problem, its causes, and effects, and propose solutions to address and resolve the problem. 

They aim to offer practical, effective solutions to real-life issues, providing a roadmap for solving problems or improving situations.

Structure of an Expository Essay

An expository essay typically comprises three main parts: the introduction, body paragraphs, and conclusion. Here's what the general structure of an expository essay looks like:

Introduction

The introduction of an expository essay is where the writer presents the topic, provides background information, and ends with a clear thesis statement . 

This section aims to grab the reader's attention and set the stage for the discussion that follows.

Body Paragraphs

The body of the essay contains a series of paragraphs that delve deeper into the topic. 

Each paragraph should begin with a topic sentence that introduces the main idea or argument. 

These paragraphs present evidence, examples, or explanations supporting the thesis statement. Smooth transitions between paragraphs ensure a coherent flow of information.

The conclusion of an expository essay restates the thesis statement using different wording. It summarizes the key points discussed in the body paragraphs. 

Finally, it offers a sense of closure, wrapping up the essay's main ideas. It's not just a repetition of earlier information but rather a synthesis of the key points to leave a lasting impression on the reader.

How to Write an Expository Essay?

Writing an expository essay involves a step-by-step process to effectively communicate information. Here's a guide to crafting an expository essay:

Select a Topic

When selecting a topic for an expository essay, it's crucial to choose something that's not only interesting but also suitable for an informative discussion. 

Consider the following pointers while choosing an expository essay topic:

  • Select a topic that personally interests you.
  • Choose a topic that can be explained within the essay's scope
  • Choose subjects allowing for an objective, fact-based analysis.
  • Consider prevalent issues or areas of curiosity for discussion.

Conduct Research

When researching for your expository essay, explore diverse and credible sources like books, scholarly articles, and reputable websites. 

Ensure the information gathered directly relates to your topic and is from reliable sources. Verify the credibility by checking the author's credentials and publication dates. 

Consider various perspectives to present a well-rounded view. Organize your findings systematically, keeping detailed notes for citation. This approach helps in crafting a well-informed and supported expository essay.

Create an Outline

Develop a structured outline for your essay. Organize your thoughts, decide on the main points, and arrange them logically.

Write The Introduction

The introduction of an expository essay plays a pivotal role in engaging the reader and setting the stage for the discussion. Here are the essential components:

  • Engaging Hook : Begin your essay with a captivating fact, question, quote, or story related to the topic to captivate the reader's attention and encourage them to continue reading.
  • Background Context: Offer essential background information about the topic, providing the necessary context for the reader to understand its relevance and importance.
  • Clear Thesis Statement: End the introduction with a clear thesis statement. It should express the main idea or argument of your essay. This statement helps guide the reader, indicating the purpose and direction of your essay.

Compose Body Paragraphs

The body paragraphs serve as the essay's core. 

Each paragraph starts with a topic sentence introducing the main idea. Back up this idea with evidence or examples to support your point. 

Make sure each paragraph smoothly connects to the next for a logical flow of ideas. This structured approach ensures a coherent and well-supported discussion throughout your expository essay.

Write the Conclusion

In the conclusion of your expository essay, recap the main points without introducing new information. 

Restate the thesis in different words to reinforce the main argument. Additionally, offer closing thoughts or discuss the broader implications related to the topic. This section serves as a summary, emphasizing the significance of the essay's ideas and their broader relevance.

Revise and Edit

Revision and editing are crucial steps in the essay writing process. 

Review the content for coherence and logical flow, ensure the essay structure is smooth and well-organized, and focus on clear, concise language. 

Check for grammar, punctuation, and spelling errors, verify citations, and seek feedback for improvements. Finally, perform a final proofread to ensure the essay is error-free and polished for submission.

Expository Essay Example

How to Write an Expository Essay

Published by Grace Graffin at August 17th, 2021 , Revised On July 26, 2023

Expository means “to describe or explain something” . It is related to the words ‘exposition’, ‘expound’, and ‘expose’ – to explain or reveal the meaning, to lay open, speak one’s mind.

Whenever there is a need to gather research and describe an idea, a  topic , or a process clearly and logically, it is done in the form of an expository  essay .

An expository essay requires the writer to take a balanced approach to the subject matter rather than justifying a particular point of view.

Expository essays are assigned to students to evaluate their subject knowledge and composition skills. When compared with  argumentative essays , they involve a lot less research.

Definition of Expository Essay

“The expository essay is the  type of essay  that involves an investigation of an idea or topic, appraises relevant supporting evidence material, and presents an argument in a clear and concise manner. ”

When to Write an Expository Essay

Your school or university could assign an expository essay to you as coursework or as part of an online exam.

However, the guidelines may or may not clearly state that your assignment is an expository essay. If that is the case, then look for keywords like ‘explain’, ‘describe’, ‘define’, etc., to be sure that what has been asked for is an expository essay.

You might even be asked to explain and emphasise a particular concept or term. Writing a simple definition will not be enough because you will be expected to explore the ideas in detail.

Writing an Expository Essay

An expository essay should not be based on your  personal  experiences and opinions. It rather takes an objective approach. You will be expected to explain the topic in a balanced way without any personal bias.

Make sure to avoid the first and second person (“I” and “You”) when writing an expository essay.

How to Structure an Expository Essay

The  structure  and format of your expository essay assignment will depend on your school’s guidelines and the topic you are investigating. However, it is always a good idea to develop an outline for your  essay  before starting to work.

The Five-Paragraph Essay Writing Approach

An expository essay will require you to take the five-paragraph essay approach: an  introductory paragraph , a main body paragraph , and a concluding paragraph . This is often referred to as the hamburger style of the essay because, like a hamburger, it contains five main parts: the introduction and conclusion being the bun that encapsulates everything.

Rationale and Thesis Statement

Start your essay  with a rationale and thesis, also known as the  thesis statement , so your readers know what you set out to achieve in your expository essay assignment. Ensure the thesis statement is narrow enough to follow the guidelines in the assignment brief. If the thesis statement is weak and too broad, you will struggle to produce a flawless expository essay.

The Framework

Construct a framework, so you know what elements will constitute the basis of your essay.

Expository Essay Introduction

Like other  essay types , an expository essay begins with an  introduction , including a hook, background to the topic, and a thesis statement. Once you have grabbed the readers’ interest, it will be easier to get them to read the remaining essay.

Frequently Asked Questions

Will i need the skill of expository writing after i finish my studies.

It depends on what you are studying for. While you might or might not write any more expository essays after your formal education has ended, the skill will be very useful in certain careers, such as business reports, journalism, and in scientific and technical writing.

How does an expository essay differ from an argumentative essay?

An argumentative essay is usually longer and requires more research. It starts with a claim about something that will need supporting evidence. And both sides of the argument need to be discussed. In an expository essay, there is no requirement to make an original argument and defend/support it.

What is the purpose of expository essays?

This style of essay is necessary when you have to showcase your knowledge on a given subject, or your ability to gather research on one and present your findings.

How long is an expository essay?

There is no fixed length but an expository essay could be part of an exam, in which case it might only be 1,000 words or less. They are usually shorter than argumentative essays . It can depend on the subject under discussion. You will likely be given instructions on the required word count.

Are there different types of expository essay?

There are six different types of expository essay, each with a different purpose.

The six types are:

Process essay – describing a task, a method, how to complete something Cause and effect essay – why something happened and its effects Problem-solution essay – provide analysis of problems and their solutions Compare and contrast essay – describe the similarities and differences between two subjects Definition essay – define the topic in detail and explain the how, what, and why Classification essay – separate the topic’s categories and define them in detail

When you are assigned your essay, you should be able to distinguish which of these approaches you are required to take.

Expository writing: how to write an incredible expository essay.

Expository essays are frequently assigned in  English classes  and are evaluated in various standardized exams.

But what exactly  is  an expository essay, and how do you write a good one?

In this article, we’ll tell you everything you need to know to pen a high-scoring expository paper.

What Is an Expository Essay?

The word  expository  means “intended to explain or describe something.”

An expository essay requires you to investigate an idea, gather supporting evidence, and present your point of view on a topic.

  • You may be wondering how this differs from a persuasive essay.
  • While both essay types require you to provide evidence to support a claim, persuasive essays are more argumentative.

A persuasive essay includes a counterargument, which addresses and rebuts an opposing viewpoint.

Expository essays, on the other hand, focus on clearly explaining and supporting  your  point of view.

Parts of an Expository Essay

A strong expository essay should consist of:

  • An introductory paragraph with a clear thesis
  • Evidence that supports the thesis (typically in three body paragraphs)
  • A conclusion

Below, we’ll look at how to construct the expository essay piece by piece.

For clarity, we’ll focus on a somewhat formulaic process for expository writing.

Once you’ve mastered these basics, you can take risks and sprinkle more creativity throughout your essays.

Introduction

The introduction frames the topic of your essay.

It also provides readers with any necessary background information or context.

A simple format for your introduction is:

  • Grabber/Hook  – A compelling sentence or two that draws readers into your essay.
  • Background Information (as needed)  – Any basic information the reader needs to know about the topic to understand your essay.
  • Thesis Statement  – This is the most important sentence of your entire essay. See below for more information.

Thesis Statement

The thesis statement is the roadmap for your entire essay, so it must be clear and concise. It should state your point of view on the topic.

  • The thesis may also  briefly  mention the supporting evidence you’ll expand on in the body of the essay.

For instance, a thesis statement might say:

Students should read more literature because it improves vocabulary, reading comprehension, and empathy.

The writer’s viewpoint is immediately clear: Students should read more literature.

The writer also indicates that her supporting evidence will mention several benefits of reading literature: improved vocabulary, better reading comprehension, and increased empathy.

  • Most likely, each of these points will form one of the writer’s body paragraphs.

If your teacher (or a standardized test) assigns you a topic, here’s another way to think of a thesis statement: The thesis is your answer to the question being asked.

  • Let’s say you receive a prompt that says, “Your community is thinking of starting a program encouraging people to limit car usage. Explain how limiting car usage would benefit your community.”

This prompt is essentially asking, “How would limiting car usage benefit your  community ?”

  • Thus, your thesis could answer the question by saying something like, “Limiting car usage would benefit the community because it would decrease traffic, improve public health, and reduce air pollution.”

This approach ensures that you’re on topic and directly addressing the prompt.

Supporting Evidence

Once you’ve clearly stated your point of view, it’s time to support it. To do this, you’ll need  evidence . Sometimes, this will mean doing your own research.

On other occasions, especially exams, you’ll be provided with relevant resources.

These may include newspaper articles, primary sources, photos, or even audio recordings.

  • Your job is to sort through these resources and find evidence that supports your thesis. It’s important to note that if you can’t find evidence supporting your thesis, you’ll need to change it.

Strong evidence may include research findings, quotes from experts, and statistics. Make sure that your evidence is from credible sources and clearly supports your thesis statement.

Organizing Evidence

After finding your supporting evidence, you’ll organize it into body paragraphs, typically three of them.

Each body paragraph should focus on one general idea.

In addition, each of these general ideas should be logically connected to your thesis statement.

  • Your body paragraphs should start with a topic sentence that introduces the idea that the body paragraph will elaborate upon.

Remember our sample thesis about students reading more literature?

  • The topic sentence of the first body paragraph could read, “To start with, reading literature is essential because it expands students’ vocabulary.”

After the topic sentence, the paragraph should introduce 2-3 pieces of evidence supporting this idea.

If a piece of evidence doesn’t clearly relate to the body paragraph’s topic sentence, it needs to be moved or deleted.

Analyzing Evidence

When you introduce a piece of evidence, follow it up with a sentence analyzing the evidence in your own words.

  • Explain the connection between the evidence and your thesis statement.
  • How does it support your point of view?
  • How do you interpret this evidence?

Remember that essays don’t only reflect your writing skills; they also reflect your critical thinking skills.

Instead of merely quoting evidence, you must also explain your thought process.

As a result, an effective body paragraph can follow this formula:

  • Topic sentence
  • Evidence #1
  • Analysis of Evidence #1
  • Evidence #2
  • Analysis of Evidence #2
  • Evidence #3 (Optional)
  • Analysis of Evidence #3 (Optional)
  • Concluding/transitional sentence

The final sentence of the body paragraph should remind readers of the paragraph’s main point and connect it to the next paragraph.

Transitions are important because they help readers follow your train of thought without confusion.

They smoothly guide readers through your paper.

Transition words and phrases include:

  • For example
  • For instance
  • To illustrate
  • Specifically
  • On the other hand
  • Consequently
  • As a result
  • Additionally
  • Furthermore

Get personalized advice!

Like stories,  essays  have a beginning, middle, and end.

  • The introduction is your beginning, the body paragraphs form the middle, and the conclusion brings the paper to an end.

The conclusion synthesizes the information included in your essay.

As the name suggests, it also draws a conclusion from the information presented.

  • Instead of simply restating the thesis, you should revisit the thesis in light of the supporting evidence you’ve provided. Do not introduce any new information in the conclusion.

Remember that the conclusion is your last chance to make an impression on the reader. It should be logical and convincing.

Try to end with a strong and/or memorable final sentence.

In total, an expository essay includes these pieces:

– Introduction

  • Hook/grabber
  • Background information

– Body paragraphs (usually three)

– conclusion.

  • Synthesis of evidence
  • Explanation of what this evidence shows (connected to thesis)
  • Strong final sentence

If you include each of these pieces, you’ll have a clear, logical, and effective expository essay.

Once you become comfortable following this formula, you may wish to vary it or infuse it with your own style.

Just make sure that all the essential pieces are present in your essay.

The Expository Essay Writing Process

Before you can effectively assemble an expository essay, you’ll need to gather information and plan your approach.

Typically, the writing process includes:

  • Carefully reading the prompt (if applicable)
  • Brainstorming
  • Gathering evidence
  • Revising/editing

Let’s take a closer look at each step in the process.

1. Reading the Prompt

If you’re provided with a prompt, understanding it is an essential first step.

Misinterpreting the prompt will result in a low score, even if your essay is well-written.

  • Read the prompt at least 2-3 times, underline key words and phrases. If the prompt is complicated, you may want to rewrite it in your own words.

Does the prompt have multiple parts? If so, make sure you understand each part and that your essay clearly addresses all of them.

2. Brainstorming

Once you’ve read the prompt, begin brainstorming how you will approach it.

  • If you’ve been provided with relevant resources, this may also include a first read-through or skimming of these texts.

What position will you take? How are you planning to support your viewpoint? Jot down any idea that pops into your head.

  • It doesn’t matter if the idea is good—right now, you’re just trying to find inspiration. You’ll change, add, or remove information later.

If you haven’t been provided with a prompt, you’ll need to brainstorm a topic that interests you.

It should also be a topic on which you’re at least somewhat knowledgeable.

3. Gathering Evidence

At this point, you’ll find evidence that supports your point of view.

  • It helps to write at least a rough draft of your thesis statement before beginning this step.
  • This way, you’ll have a clear idea of what sort of evidence you need to find.

After writing your thesis statement, find credible evidence that supports it.

  • This may require you to go to the library or browse scholarly databases on the Internet.

Alternatively, you may have been provided with resources.

In that case, read through the resources carefully, underlining or circling evidence that reinforces your thesis.

4. Planning

Planning ensures that your essay is organized, focused, and cohesive.

It also allows you to catch potential mistakes  before  they happen.

  • For instance, you might realize that some of your evidence doesn’t fit, or that one of your body paragraphs is lacking support.

You can then address these areas of weakness before writing your essay.

  • At the top of your planning sheet (or a document on your computer) write your thesis statement.
  • Continually reference the thesis to ensure that you’re focused and on topic.
  • Next, determine the focus of each body paragraph and the 2-3 pieces of evidence that will support it.

Sometimes, students think that planning is too time-consuming.

However, a plan will save you time in the long run.

With all your quotes and evidence organized in one place, writing your essay is much faster and easier.

Once you have a completed plan, begin writing your essay.

  • Remember to analyze each piece of evidence and clearly connect your points with transitions.

Use a formal, academic tone and avoid slang or overly casual language.

Vary your sentence structure, including both short and long sentences. Pay attention to spelling, grammar, and punctuation.

6. Revising

Students often skip the revising and editing step of the writing process.

This is a mistake. Slowly read through your essay  at least  once before submitting it.

  • Look for misspelled words, incorrect verb tenses, and punctuation or grammar mistakes. Does your writing flow well? Does everything make sense?
  • Are all of your points clear? Have you used the same word or phrase repetitively? (If you have, try to substitute a synonym.) Did you use transitions connecting your ideas?

Ensure that you submit the best, most polished version of your essay possible. Mistakes and unclear sentences make a poor impression.

Advice From the Experts:

From Dr. Carrie Brown, professor of English and creative writing at Sweet Briar College and novelist :

When I’m working with students on expository writing — on writing in any rhetorical mode, really — I remind them that almost inevitably they have to stumble their way through some lousy sentences before they discover what they actually want to say. (This takes us back to that famous question: How do I know what I mean until I see what I say?) Some messy writing usually precedes orderly, elegant writing, and every writer needs patience during that messy process, because that process is important: out of that process emerges clear thinking, which is the true key to clear writing. Once  writers have waded around in the muck for a while, then they can step back and examine those sentences or numbered phrases or bulleted points — whatever method felt most natural to the writer by which to set down emerging thoughts — to discover which are relevant, which are simply repetitions of earlier thoughts, which are superfluous or meaningless, and in what order they ought to proceed. A trick that seems to work for students with a strong tendency toward auditory learning can actually record themselves speaking aloud, trying to address the topic, and then play back that recording, meanwhile transposing ideas — and usually improving and clarifying them — as they go.

From Adam Cole, author and writing expert:

Know your audience – Whatever you are writing, you will get the best results if you are thinking about who is reading it, why they are reading it, and what you should do to make sure the interaction between you and the reader is optimal. While the audience for an expository piece may be obvious, writing directly to that audience is not so obvious. It affords you an opportunity to think clearly and write clearly without having to worry about your identity, ego or success. If you are in school, the audience for expository writing is your professor, and you should be fulfilling the boxes in their rubric to the letter. If they haven’t given you a rubric, ask for one. If they won’t, find one or create one based on conversations with them, their former students, or another professor.

From Tangela Walker-Craft –  Simply Necessary, Inc. , Family and Parenting Blogger:

Write in complete sentences. Write in paragraph form. Each paragraph should contain 3 to 5 sentences for short essay questions, and 5 to 10 sentences for long essay questions. Vary sentence length and structure; try not to begin sentences with the same word or words. Use facts and information taken from reading passages to answer questions; refer back to the reading passage to stay focused. Underline important information in reading passages to make it easier to go back to them when answering questions. Proofread. Proofreading sentences backwards makes finding spelling mistakes and punctuation errors easier because it forces test-takers to focus on individual words instead of automatically “seeing” what he or she intended to write.

From Peter Donahue,  a writing expert  and teacher:

1. Write for clarity, not formality. As a teacher, I see a lot of expository writing where the writer is more concerned with following the conventions of academic jargon than she is with expressing ideas. A good example is the use of “utilize” instead of “use,” because it “sounds more formal,” or the avoidance of the pronoun “I” because it “sounds too informal.” So, rather than trying to appear formal, expository writing should aim to be clear. George Orwell’s 1946 essay, “Politics and the English Language,” says more on this topic, and is a worthwhile read. 2. Think synthetically, write analytically. Synthetic thinking starts with small details, or an open-ended question. As thoughts continue to develop, the main idea is clarified (or discovered) at the end the process. Contrariwise, Analytical thinking starts with a “given:” a major premise or generalization. It then proceeds to break down the main idea into its components and deal with each separately. Expository writing is usually presented most effectively in an analytic format — the main idea first, the support afterwards. On the other hand, literary writing, like a poem or discursive essay, is often presented synthetically. The key is knowing the difference between thought process and written format. We can think something synthetically, and then write it analytically. And in fact, this process can be the key to effective expository writing for many people. Don’t assume that because a thesis appears in the first paragraph, you have to think of it first. You could try drafting it synthetically, to clarify your thinking. Then rewrite it analytically to present it more effectively for your reader.

From Jessica Moody,  curriculum expert :

Expository writing is first about structure, second about clarity, and third about content.  Depending on the type of expository writing there is a specific structure expected.  Even in college essays each sentence on the essay has a purpose and can be labeled as a thesis statement, topic sentence, evidence, or explanation of evidence. If the structure is not there, most of the time there is not much clarity and the content is lacking because it is confusing.  This is the same for any type of expository writing. My suggestion for people becoming better at expository writing is to study the structure of the piece, the paragraph structures and the sentence structures.  If you understand how to break down the structure then you can learn to replicate any style or form you want.

Text evaluation and analysis usually start with the core elements of that text: main idea, purpose, and audience.  An author needs to consider all three of these elements before writing, as they help determine the author’s content and language.  As a reader, it’s important to ascertain these aspects of a text which exist as a foundation for the author’s content and language.

Always start with the main idea.  Main ideas may be stated directly in the text or implied; you need to read a text carefully in order to determine the main idea. Put the main idea into your own words, so that it’s expressed in a way that makes sense to you.  Then ask and answer the following basic questions about that main idea:

  • Is the main idea reasonable/believable to most readers?
  • Is the main idea clear and if not, why do you think the author embedded it?
  • Is the main idea the author’s opinion, or is it something that the author asserts about an issue?

Asking and answering these questions should help you get a sense of the author’s intention in the text, and lead into considering the author’s purpose.

Main idea and purpose are intricately linked. There are a few basic purposes for texts; figuring out the basic purpose leads to more nuanced text analysis based on its purpose. Basic purposes of a text include:

  • to inform – to describe, explain, or teach something to your audience
  • to persuade/argue – to get your audience to do something, to take a particular action, or to think in a certain way
  • to entertain – to provide your audience with insight into a different reality, distraction, and/or enjoyment

The following video more fully explains these different purposes of a text, and adds a fourth, to share insights or feelings.

Main Idea & Purpose Determine Analysis

The author’s main idea and purpose in writing a text determine whether you need to analyze and evaluate the text.  They also determine the pieces of the text you should analyze—content or language or both.

If the purpose is to persuade or argue

You always need to analyze the text to see if the main idea is justified.  Do the supporting ideas relate to and develop the main idea? Is the supporting evidence taken from recognized, valid sources?  Is the author arguing via language instead of evidence or facts?  Persuasion and argument need to present logically valid information to make the reader agree intellectually (not emotionally) with the main idea.

If the purpose is to inform

You usually need to analyze the text, since the text needs to present valid information in as objective a way as possible, in order to meet its purpose of explaining concepts so a reader understands.

If the purpose is to entertain

You may or may not need to analyze the text. Writing that entertains does not necessarily have to be either logical or complete in order to accomplish its purpose. You may want to analyze the text for language, though, to see how the author manipulates language to accomplish their purpose.

Who are the author’s intended readers?  Figuring out this will help you understand an author’s approach to providing the main idea with a particular purpose. Does the audience know little or nothing about the topic, or are they already knowledgeable?  Is the audience’s knowledge at beginner or expert level, somewhere in between, or mixed? Does the audience include people who may be skeptical of the author’s ideas?  Does the audience include people who outright oppose the author’s ideas? As you can see, asking and answering questions about audience can help an author determine the type and amount of content to include in a text. As a reader, it’s important to figure out the author’s intended audience, to help you analyze the type, amount, and appropriateness of the text’s information.

The following video presents the concept of audience from a writer’s perspective, but the concepts are applicable to you as a reader who needs to consider audience as a foundation for evaluating a text.

You may also want to link to one of Purdue’s Online Writing Lab’s page on Author and Audience to get a sense of the wide array of variables that can influence an author’s purpose, and that an author may consider about an audience.

Read the article “ Forget Shorter Showers ” by Derrick Jensen.

Note that most of the Try It exercises in this section of the text will be based on this article, so you should read carefully, annotate, take notes, and apply appropriate strategies for reading to understand a text.

Then answer the following questions about the article’s main idea, purpose, and audience.

Which selection best represents the author’s main idea?

  • We have it in our power and right to take action to stop the industrial economy over-using and wasting our natural resources.
  • We are victims of a campaign of misdirection, being told and accepting that our personal use of natural resources is both the cause of scarcity and the solution to preservation.
  • Because we have accepted our identities as consumers, we reduce our forms of political existence to consuming and not consuming.
  • Simple living is better for the planet than over-consumption.

Sentence 1 is the best answer. Although sentences 2 and 3 extract main ideas from the text, they are key supporting points that help lead to the author’s conclusion and main idea.

Which selection best represents the author’s purpose?

  • to inform readers about the actual use of resources by individuals vs. the industrial economy
  • to persuade readers to consider taking action against an unjust situation that assigns blame to individuals instead of big business in regard to the depletion of natural resources
  • to persuade readers to re-think their personal attempts to live more simply and more “green”
  • to entertain readers interested in nature with accusations against the industrial economy

Selection 2 best represents the author’s purpose. The author’s purpose is to get readers thinking about conservation of resources in order to spur them to action against a system that, in his opinion, exploits those resources as well as individuals. His purpose is both to inform and persuade, but persuasion seems to take precedence, as he both starts and ends with a reminder about historically justified instances of activism.

Who comprises the author’s audience and what cues can you use to determine that audience?

The author is writing to an audience of readers who are interested in nature and conservation. If you look on the Orion website and read the “About” section on Mission and History, you’ll see that this publication started as a magazine about nature and grew from there. Based on reading the text, the author’s intended audience has the following characteristics:

  • Educated – The author assumes that readers know about WWII, the Civil Rights Act of 1974, and other historic events.  The author also uses language such as “systematic misdirection,” “solar photovoltaics,” and even “consensus” (instead of agreement).
  • Concerned about the environment – because they are reading this magazine in the first place
  • Willing to entertain the idea of taking action to improve quality of life and preserve resources
  • Comfortable enough (with themselves? with their social status? with their personal philosophies?) to feel that their voices might make a difference if they choose to protest the current use of natural resources
