A complex sentence is a type of sentence that contains one independent clause and at least one dependent (or subordinate) clause. The independent clause can stand alone as a complete sentence, while the dependent clause cannot. Dependent clauses often begin with subordinating conjunctions such as "because," "although," "since," "if," "when," and "while."
Example of a complex sentence:
- "Although it was raining, we decided to go for a walk."
In this example, "we decided to go for a walk" is the independent clause, and "Although it was raining" is the dependent clause. The dependent clause provides additional information but cannot stand alone as a complete thought.
