Answer:
The purpose of an informative essay is to educate others on a certain topic. Typically, these essays will answer one of the five W's: who, what, where, when, and why. Of course, they can also answer "how," indicating how to do something.
Informative essays must never express your opinion or try to convince others to take a certain action or stance. That role is expressly reserved for persuasive essays.
The basic structure of an informative essay is very simple. It needs to have a beginning, middle, and end. These are known more formally as the introduction, body, and conclusion, respectively.
