Expository essays are structured to inform and explain. They consist of an introduction with a hook and thesis, body paragraphs with topic sentences and evidence, and a conclusion that summarizes key points.

Different types of expository essays serve unique purposes. Compare and contrast essays analyze similarities and differences, cause and effect essays explore reasons and consequences, and process analysis essays describe step-by-step procedures.
