Understanding Dependent & Independent Clauses

Independent Clause: A group of words that can stand alone as a complete sentence. It has a subject and a verb and expresses a complete thought.

Example: “He travels every summer.”
» Subject = He, Verb = travels, and it’s a complete statement.

Dependent Clause: A group of words that also contains a subject and a verb, but does not express a complete thought. It needs an independent clause to make it complete.

Example: “Because he travels every summer...”
» Subject = he, Verb = travels, but it’s not a full statement on its own.

Complex Sentence: Has one independent clause and at least one dependent clause.
Compound-Complex Sentence: Has at least two independent clauses and at least one dependent clause.

Additional Examples:
