A complex sentence is a sentence that consists of one independent clause and at least one dependent clause, which are connected to each other with a subordinating conjunction
. The independent clause is a complete sentence that can stand alone, while the dependent clause is not a complete sentence and relies on the independent clause to form a complete thought. Complex sentences are commonly used to provide more information, explain or modify the main point of a sentence, and to show relationships between ideas. They often use subordinating conjunctions such as "because," "since," or "although" to connect the clauses.
