Here are just a few key points to remember. Adjective clause- is a subordinate clause that modifies a noun or pronoun by telling what kind or which one. Adjective clauses usually begin with a relative pronoun, such as that, which, who, whom, or whose. Sometimes, they may begin with a relative adverb, such as before, since, when, where, or why. Adverb clause- is a subordinate clause that modifies a verb, an adjective, an adverb, or a verbal by telling where, when, in what way, to what extent, under what condition, or why. All adverb clauses begin with subordinating conjunctions. Commonly used Subordinate conjunctions: –After, although, as, as if, as long as, because, before, even though, if, in order that, since, so that, than though, unless, until, when, whenever, where, wherever, while. It is easy to identify these clauses because they can be taken out of the sentence.
