What type of sentence contains one independent clause and at least dependent clause?

A complex sentence contains one independent clause and at least one dependent clause. The independent clause expresses a complete thought, while the dependent clause cannot stand alone and is often introduced by subordinating conjunctions like "although," "because," or "when." For example, in the sentence "Although it was raining, we decided to go for a walk," the independent clause is "we decided to go for a walk," and the dependent clause is "Although it was raining."
