The argumentative essay is an essay in which you try to convince readers to accept the argument you make. Through writing facts that back up your opinion or stance, you attempt to get readers to agree with your thinking. It often involves answering a question by taking one position over another.
Writing an argumentative or persuasive essay is about selecting a topic that has two clear sides or positions. You approach the topic by investigating it and collecting, generating, and evaluating supporting evidence. An argumentative essay also acknowledges the opposing viewpoint.
