An expository essay follows a five-paragraph structure: an introduction with a thesis, three body paragraphs each covering one supporting point with evidence, and a conclusion that restates the main idea.
The introduction should present background context before narrowing to a clear thesis statement that outlines the three points you will explain. Avoid personal opinion; expository writing explains a topic objectively using facts and examples rather than argument.
For a topic such as the causes of climate change, each body paragraph should open with a topic sentence, then explain one cause with evidence before linking back to the thesis, following the same core essay structure principles throughout.
Explanatory essay and expository essay refer to the same format, though UK schools sometimes use discursive or explanatory as alternative labels for the task at GCSE and A-level. Always check your assignment brief for exact structural requirements.
Longer expository assignments at university level may extend beyond five paragraphs to cover more points in depth. If structuring feels difficult, our model essay service can provide a model answer showing clear expository organisation.
