What Is an Expository Essay?

An expository essay has three basic parts: the introduction, the body, and the conclusion. Each is crucial to writing a clear article or effective argument.

The introduction: The first paragraph is where you’ll lay the foundation for your essay and give the reader an overview of your thesis. Use your opening sentence to get the reader’s attention, and then follow up with a few sentences that give your reader some context for the information you’re about to cover.

The body: At a minimum, include three to five paragraphs in the body of your expository essay. The body could be considerably longer, depending on your topic and audience. Each paragraph begins with a topic sentence where you state your case or objective. Each topic sentence supports your overall thesis statement. Then, each paragraph includes several sentences that expand on the information and/or support the topic sentence. Finally, a concluding sentence offers a transition to the following paragraph in the essay.

The conclusion: The final section of your expository essay should give the reader a concise overview of your thesis. The intent is not merely to summarize your argument but to use it as a means of proposing further action, offering a solution, or posing new questions to explore. Don’t cover new material related to your thesis, though. This is where you wrap it all up.

Expository Examples

An expository article or report about a lake, for example, could discuss its ecosystem: the plants and animals that depend on it along with its climate. It could describe physical details about its size, depth, amount of rainfall each year, and the number of tourists it receives annually. Information on when it was formed, its best fishing spots, or its water quality could be included, depending on the audience for the piece.

An expository piece could be in third person or second person. Second-person examples could include, for example, how to test lake water for pollutants or how to kill invasive species. Expository writing is useful and informative.

In contrast, someone writing a creative nonfiction article about a lake might relate the place to a defining moment in his or her life, penning the piece in first person. It could be filled with emotion, opinion, sensory details, and even include dialogue and flashbacks. It’s a much more evocative, personal type of writing than an expository piece, even though they’re both nonfiction styles.
