Join the two independent clauses to make a complex sentence. Use one of the subordinating conjunctions (after, although, as, as if, because, before, even if, even though, if, if only, rather than, since, that, though, unless, until, when, where, whereas, wherever, whether, which, and while).
Certain prepositions (after, as, before, since, until) serve as subordinating conjunctions when they're followed by a clause: 1  You better get out of town before sundown. (Before is used as a preposition.) 2  Many people run out of ideas long before they run out of words. (Before is used as a conjunction.)
