Sentences: Simple, Compound, and Complex

SIMPLE SENTENCE :A simple sentence, also called an independent clause, contains a subject and a verb, and it expresses a complete thought.

COMPOUND SENTENCE:A compound sentence contains two independent clauses joined by a coordinator. The coordinators are as follows: for, and, nor, but, or, yet, so. (Helpful hint: The first letter of each of the coordinators spells FANBOYS.)

COMPLEX SENTENCE:A complex sentence has an independent clause joined by one or more dependent clauses. A complex sentence always has a subordinator such as because, since, after, although, or when or a relative pronoun such as that, who, or which.
