Answer:
Complex-Compound clause
Step-by-step explanation:
A complex-compound clause is a type of clause that exists in a sentence where there are two or more independent clauses in addition to one or more dependent clauses. A complex-compound clause is also called compound-complex. Asides from having a subject and a verb, dependent clauses contain a subordinating conjunction or similar word. One example of the complex-compound clause is that
The lecturer always comes to his lectures fully prepared.
