Simple, Compound, or Complex?

A great explanation from Lola about the differences between simple, compound and complex sentences.

• Simple - a sentence with a subject, verb, and one idea.
• Compound - two simple sentences joined into one sentence with a conjunction. Both parts of the sentence can stand alone.
• Complex - a simple sentence that has an extending phrase. It has a part that makes sense on its own and a part (the extending phrase) that doesn't make sense on its own.
