More about clauses...

clause – group of words that contains a subject and verb

• independent clause: expresses a complete thought (a complete sentence is a clause!)
• dependent clause – does not express a complete thought.

Two roles* that clauses can play in a sentence:

• adverb clause (acts as an adverb)
• adjective clause (acts as an adjective)

* ...and there are more!

Simple sentence: one independent clause

• My uncle baked some cookies.

Compound sentence: two independent clauses joined by a conjunction (such as and, or, but)

• My uncle baked some cookies and he took them to work.
