And adjectival clause always includes an

An adjectival clause will always meet three requirements:

1. it will contain a subject and verb

2. it will begine with a relative pronoun (who, whom, whose, that, or which)

3. it will function as an adjective, answering the questions what kind? how many? or which one?
