This document discusses coordinating conjunctions and their proper use in sentences. It defines coordinating conjunctions as connecting words, phrases, or groups of words that should be equal or similar. There are seven coordinating conjunctions in English - FANBOYS (for, and, nor, but, or, yet, so). Rules for using coordinating conjunctions include placing a comma before the conjunction when connecting two independent clauses, but not when connecting two items that are not complete clauses. When using a coordinating conjunction in a list of three or more items, including or omitting a comma before the conjunction is optional.
