This document defines and provides examples of compound sentences. A compound sentence joins two independent clauses with a coordinating conjunction like "and", "but", or "or" or with a semicolon. Independent clauses can stand alone as sentences and contain a subject and verb. Choppy sentences can be improved by combining independent clauses into compound sentences. The document demonstrates how to identify independent clauses and provides examples of compound sentences using coordinating conjunctions and semicolons.
