The format of an expository essay allows for the clear and logical explanation of complex information instead of proving a point or providing the writer's personal opinion on a subject. Expository writing is a valuable skill in many fields of work, including journalism, business, science.

How to Write an Expository Essay

Write your expository essay in MLA format and follow a basic five paragraph structure.

1. Prewrite and Outline.

To write a well-organized five-paragraph essay, it's important to take some time to jot down pertinent notes and perform research about your expository essay topic. Once you’ve had time to brainstorm, create a basic expository essay outline that details what information you plan to include in each paragraph. Before moving on to your first draft, remind yourself to write in the third person to ensure that you don't accidentally state your own personal opinions.

2. Write an Introductory Paragraph.

Your first paragraph should include a topic sentence that clearly states your thesis or main point of the essay. A good thesis should be simple enough that you can capably support it with three body paragraphs.

3. Write Three Body Paragraphs.

Each paragraph in the body of the essay should focus on its own distinct issue that helps develop and support the thesis statement in your topic sentence. Make sure you're using factual information to support your thesis and are maintaining an objective point of view.

4. Write a Concluding Paragraph.

This paragraph should only contain information you’ve already presented earlier in the essay. Use this space to restate your thesis, summarize your supporting points from each body paragraph, and wrap up your essay.

5. Revise and Proofread.

Reread your essay and double check that your thesis is clear and supported with evidence from credible sources. Make sure you present all information in a completely unbiased way. Work to create paragraph transitions that are fluid and logical. Lastly, proofread to fix grammatical errors and poor word choices.
