The author's purpose is his or her reason for writing a text, paragraph, or line. There are many reasons why people write paragraphs or lines, but when we look at why people write texts, there are three main reasons. These are to entertain, persuade, and inform.

And examples of texts written to inform include encyclopedia entries and text books.
