Explanation:

A compound sentence is a sentence that is composed by two simple sentences that are joined by a conjunction (and, but, or). A complex sentence, on the other hand, is a sentence that is created by using a simple sentence and a subordinate clause. Therefore, a compound complex sentence is one which combines these characteristics: it is a compound sentence with a subordinate clause.
