The purpose is the reason for why someone has done a writing. There could many different reasons why someone wrote something. For example, it could be to inform, entertain, persuade, or explain something. Purpose is one of the most important aspects of writing. If you know your purpose, you can easily decide what the genre of the writing should be as well because a genre also helps get your purpose across. For example, when we were writing our technical descriptions, we couldn’t write our product as if it was something the audience was already familiar with even if we were. We had to write the description from the simple stuff to the more advanced. My purpose for the technical description was, “My purpose of writing this technical description was to spread information with something that I am very comfortable to those who aren’t and are interested.”
