There are four different types of writing: expository, persuasive, descriptive and narrative. While one could say that descriptive could describe a particular subject, craft, or occupation, descriptive writing is more for describing a character, event, or special place. Persuasive is trying to persuade your audience to think one way, and narrative is used to tell a story. Expository writing is used to communicate specific information about a particular subject, craft, or occupation.
