A COMPLEX SENTENCE includes both a subordinate clause and an independent clause. Log in to see link for more information. Added 7/16/2014 7:46:19 PM. This answer has been confirmed as correct, not copied, and helpful.
There are two kinds of clauses: independent and dependent clauses. Most simply, an independent clause can form a complete sentence on its own and a dependent clause cannot (at least, not by itself).

Caffeine lovers are dependent on coffee, so the two can be joined (quite happily) to form a cohesive unit. Similarly, two cups of coffee, or two independent clauses, can be combined.
