Answer:
compound complex sentences are sentences linked by a connector.
Explanation: A compound complex sentence is structured by simple sentences linked by different type of connectors.
The compound complex sentence is named and cathegorized by its connector.
Therefore there are coordinated, adverb, noun and adjective compound complex sentences.
If the connector is a conjunction as "and", "or", "but" it is a coordinated or correlative compound complex sentence. It is used to list or relate series of actions.
If the connector is an adverb then it is an adverb compound complex sentence. It is used to describe or extend the main action.
If the connector is an adjective then it is an adjective compound complex sentence. It is used to expand the description of the main noun.
If the sentence completes another sentence as if it was a noun then it is a noun compound complex sentence.
