What Are Complex Sentences?

A complex sentence is a type of sentence that contains one independent clause and at least one dependent clause. The dependent clause provides additional information but cannot stand alone as a complete sentence.

Understanding Complex Sentences

A complex sentence combines an independent clause with one or more dependent clauses. An independent clause can stand alone as a sentence, while a dependent clause cannot.

The dependent clause provides additional information and cannot function as a complete sentence by itself.

Example: "I went to the park because I wanted to relax."

  • Independent clause: "I went to the park."
  • Dependent clause: "because I wanted to relax."

In this example, the independent clause "I went to the park" expresses a complete thought. The dependent clause "because I wanted to relax" adds more context but cannot stand alone.
