Subordinating Conjunctions

Subordinating conjunctions are words that link a main clause (a sentence that can stand alone) with a dependent clause (a clause that needs another sentence to be complete). They help us show time, cause, reason, contrast, condition, and purpose in sentences. These conjunctions introduce extra information and explain when, why, or under what condition something happens.
