Explanation:

A complex sentence is one that has an independent sentence (which is a sentence that has meaning in its own right and does not need a complement to have meaning) linked to a dependent sentence (which is a sentence that has no meaning alone and needs a complement) to make sense) through a conjunction, adverb, relative pronoun, or other.

A compound-complex sentence is a sentence that has two or more independent sentences linked together by conjunctions, or by commas.
