Question

what is adjective clause?

Answer 1

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? or Which one?

Answer 2

ex. fond of pecans (these are frags)
you can see that "fond" is the head word because "of pecans" is answering the "what" question for fond. this whole phrase is held by the adjective.

Answer 3

another example is "happy to be moving to a new town"
