The main difference between an expository essay and an argumentative essay is the purpose and approach of the writing.
An expository essay is meant to inform or explain a topic or idea to the reader. It presents factual information and evidence on a particular subject without expressing any personal opinion or argument. The writer aims to explain the topic clearly and objectively, often using examples, statistics, or research to support their claims.
An argumentative essay, on the other hand, is written to persuade the reader to accept the writer’s viewpoint or argument on a particular topic. It presents a claim or argument on a debatable issue, provides evidence and reasoning to support it, and often refutes opposing viewpoints. The writer tries to convince the reader to agree with their perspective.
