How to Determine the Purpose of an Author's Work?
In every literature out there, a purpose is hidden behind them. If someone has written a novel, there's always a story behind it. However, as readers or even writers, you need to understand the purpose of the writeup. Any author's purpose can fit in any of these categories, i.e., PIE (Persuasive, Informative, Entertain). Usually, research papers and books about sciences are persuasive. These kinds of texts must be understood critically. Now, if it's a factual paper, then the author wants the readers to understand facts and figures about anything. Informative magazine articles can help you understand different concepts. There are research papers as well, which helps in increasing our knowledge or textbooks in general. The entertaining purpose is simply that of a novel. Entertainment doesn't necessarily mean that the genre needs to be funny. Any kind of text that triggers an emotion in our mind can be an entertaining piece of text.
