A compound sentence contains two simple sentences joined by a comma and a joining word. Joining words are and, but, and or. For example: She wanted to play outside, but it was raining. Be careful not to confuse compound sentences with sentences that have compound predicates. A compound predicate associates two or more verb phrases with a simple subject. For instance: Paul brushed his teeth and went to bed.
