An expository essay is a type of writing that aims to explain, inform, or describe a specific topic. It presents facts, statistics, and examples to help the reader understand the subject clearly. Unlike persuasive essays, expository essays do not include the writer's opinions or emotions; they focus solely on delivering objective information. Typically structured with an introduction, body paragraphs, and a conclusion, expository essays can cover a wide range of topics, such as science, history, or literature. This format allows writers to organize their thoughts logically, making it easier for readers to follow and comprehend the information presented.
