Adjective Clause

An adjective clause—also called an adjectival or relative clause—will meet three requirements:

• First, it will contain a subject and verb.
• Next, it will begin with a relative pronoun [who, whom, whose, that, or which] or a relative adverb [when, where, or why].
• Finally, it will function as an adjective, answering the questions What kind? How many? orWhich one?

The adjective clause will follow one of these two patterns:

relative pronoun or adverb + subject + verb

relative pronoun as subject + verb

Adjective clause start with relative pronoun or relative adverb.
