Clauses and Phrases


  • A clause is a group of words containing a subject and verb. An independent clause is a simple sentence. It can stand on its own.

She is hungry.
I am feeling well today.

  • A dependent clause cannot stand on its own. It needs an independent clause to complete a sentence. Dependent clauses often begin with such words as although, since, if, when, and because.

Although she is hungry …
Whoever is hungry …
Because I am feeling well …

Dependent Independent
