Structure of an Expository Essay


The introduction serves as the gateway to your essay. It should grab the reader’s attention with a hook, provide necessary background information about the topic, and present a clear and concise thesis statement. The thesis statement is crucial as it outlines your essay’s main point.

Body Paragraphs

The essay’s body typically consists of three or more paragraphs; each focused on a specific aspect or subtopic related to your thesis statement. Here’s the basic structure of a body paragraph:

Topic Sentence: This sentence introduces the main idea of the paragraph.

Supporting Evidence: Provide facts, examples, statistics, or quotations to help your topic sentence.

Explanation: Explain how the evidence supports your thesis and the significance of the information presented.

Transition: Use transitional words or phrases to connect one paragraph to the next smoothly.
