A subordinate clause includes a subject and a verb, cant stand alone in a sentence because it doesn't convey a complete idea. But in order for it to form a complete idea, a subordinate clause MUST BE combined with an independent clause. It can be attached before or after the subordinate clause. An Independent clause can stand alone in a sentence and its a complete sentence. Hence Independent meaning can survive alone therefore, which clause is underlined? but here's what you should know Steve is going downtown so that he can buy some sneakers. Subordinate clause: so that he can buy some sneakers If you leave that sentence alone, it becomes a fragment. This explains how subordinate clauses cant stand alone as a sentence. Independent clause: Steve is going downtown This part of the sentence is independent and can survive alone without the other half or the subordinate clause attached to it.
