Sentences are a series of words that complete a thought. All sentences contain a subject and a predicate. The subject is who or what of the sentence. You can locate subjects by looking for the action word (verb), the who or the what that is performing that action is the subject. The section of the sentence that modifies the subject is called the predicate. The predicate always includes the verb of the sentence. Sentences can present as basic statements, commands, exclamations, or questions.

Complete sentences have several characteristics. They begin with a capital letter and end with a mark of punctuation. The punctuation mark indicates the nature of the sentence. A question mark tells it is a question. A period indicates a statement or command. An exclamation point tells us it can either be a cry out or command.
