Simple sentence: Cookies are not healthy treats.
Compound sentence: I love cookies, but they are not healthy treats.

A complex sentence is a sentence joined to a fragment with a conjunction or transition word. Remember, a fragment does not make sense on its own.

Fragment: Until they were clean.
Complex sentence: I brushed my teeth until they were clean.
The fragment "until they were clean" doesn't make sense on its own.
Simple sentence: Joe left for the park.
Fragment: After his mom got home.
Complex sentence: Joe left for the park after his mom got home.
