Grammar Lessons: Complex Sentences

Complex Sentences

In grammar, Complex Sentences is a sentence with one independent clause and at least one dependent clause.

A complex sentence is often used to make clear which ideas are most important, and which ideas are subordinate.

Independent Clause

An independent clause (or main clause) is a clause that can stand by itself as a simple sentence. An independent clause contains a subject and a predicate and makes sense with another word(s).

Dependent Clause

dependent clause is a clause that provides a sentence element with additional information, but which cannot stand alone as a sentence. A dependent clause can either modify an adjacent clause or serve as a component of an independent clause.
