A complex sentence consists of an independent clause and a dependent clause joined together.
An independent clause is a group of words that has a subject and a verb and is a complete thought. An independent clause can stand on its own as a sentence.
A dependent clause is a group of words that has a subject and a verb but is not a complete thought and can't stand on its own as a sentence.
