An expository essay has the same structure as a regular essay, with an introduction, body and conclusion or summary. An expository essay should present the subject in detail. The writer cannot assume the listener or reader has prior understanding or knowledge of the topic in discussion.
The best way for a writer to elucidate a subject is by first analyzing it the presenting the text in an organized manner. In order to fashion a good expository essay, the writer should:
- Choose a topic: should be narrow enough to cover within a few pages.
- Find suitable sources: must be reliable and fully cover the topic.
- Write a clear and concise thesis statement: thesis sentence appears in the first paragraph and expresses a controlling idea that is neither too specific nor too broad.
- Organize the essay: usually has five paragraphs, an introduction, three body paragraphs and a conclusion. The transition between each paragraph should be logical and clear.
Each body paragraph should feature a topic sentence that relates to the thesis statement. The concluding paragraph must reiterate the divisions and thesis of the essay, avoid deviating into new topics, and bring the expository essay to an effective and appropriate close.
