In what way is expository essays different from business communication?" This question is one that is commonly generated from undergraduate classes (lower division) curriculum and is answered in the text books that go with that course. On the off chance that this is a burning question for some individual, here is the answer. Expository writing is writing that is meant to expose something. To tell how it works, what this something is about or explain to others how to perform something. Based on facts, this style of writing uses the facts to show how what is being written about is done or accomplished. Expository writing is the most common form of writing used in the academic environment and usually is coupled with some style of format, APA, MLA, Turabian. Business writing has two main parts, the explanation (much like expository writing) and the direction, or what you are supposed to do, the action you need to take. It can be seen that the difference is based on the audience and the writer as business writing will expect an action or reaction and expository writing is more academic and for the purpose of spreading knowledge.
