Question

What is a compound-complex sentence in simple words please :)

Answer 1

Example: Because the soup was too cold, I warmed it in the microwave.
A compound-complex sentence is just comprised of at least two independent clauses and one or more dependent clauses. Example: Though Mitchell prefers watching romantic films, he rented the latest spy thriller, and he enjoyed it very much.

Answer 2

"Though Mitchell prefers watching romantic films, he rented the latest spy thriller and enjoyed it very much."

There is one dependent clause:

"Though Mitchell prefers watching romantic films"

and two independent clauses connected (in this case) with an "and":

"he rented the latest spy thriller and enjoyed it very much."
