What are the conjutions of a complex sentence?

In a complex sentence, conjunctions connect dependent clauses to independent clauses. The primary conjunctions used are subordinating conjunctions, such as "because," "although," "since," "when," and "if." These conjunctions help establish the relationship between the clauses, indicating causality, time, condition, or contrast. For example, in the sentence "Although it was raining, we went for a walk," "although" is the subordinating conjunction linking the dependent clause to the independent clause.
