Answer:
Clause
Explanation:
subordinate, or dependent, clause contains a subject and predicate but cannot stand alone. This type of clause must be used with a main clause in order to make sense. It usually begins with a subordinating conjunction, such as after, although, as, as if, because, if, since, so that, than, unless, until, when, where, or while; a relative pronoun such as who, whose, whom, which, that, or what; or a relative adverb, such as when, where, or why.
