Asentence that includes an independent clause and at least one dependent clause is called a sentence.

A complex sentence

Explanation:

A complex sentence is a type of sentence made up of one independent clause (one that expresses a complete thought) and at least one dependent clause (one that can not stand alone as a sentence because it does not express a complete thought).

In this type of sentence, the dependent clause is often introduced by a coordinating conjunction such as even though, when, after, while, because, since, if and until. Here are some examples (independent clauses underlined):
