Many different types of writing exist in the world, ranging from classic Shakespearean plays to politicians' speeches to the screenplay treatments that inspired this summer's biggest blockbuster hits. These works may vary in tone, genre and type, but as pieces of writing, they should have one thing in common: a purpose.

Authors write for many different reasons. Those reasons are called the author's purpose. Depending on the purpose, authors may choose all different sorts of writing formats, genres and vernacular. A simple trick to summarize the three main categories of author's purpose is to use the acronym PIE, which stands for persuade, inform and entertain. Although there are many reasons to write, to persuade, to inform and to entertain represent the three main forms of author's purpose.
