"Purpose is the goal or aim of a piece of writing: to express oneself, to provide information, to persuade, or to create a literary work. There are four purposes writers use for writing. When someone communicates ideas in writing, they usually do so to express themselves, inform their reader, to persuade a reader or to create a literary work."
