What is the purpose when you write an argument?

The purpose of writing an argument is to present a viewpoint or position on a particular topic or issue and to persuade the reader to agree with or consider that viewpoint. It aims to provide logical reasoning, evidence, and support to convince the audience of the validity of the argument being made. Additionally, writing an argument helps to engage in critical thinking, analyze different perspectives, and promote open and thoughtful discussions about the topic at hand.
