Adjective Clauses

Look at the groups of words in italics in the following sentences:-
1. The umbrella with a broken handle is mine. [Which umbrella?]
2. The umbrella which has a broken handle is mine. [Which umbrella?]
The first group of words, with a broken handle, describes the umbrella; that is, it qualifies
the noun umbrella, and does the work of an Adjective. It is what we call an Adjective
phrase.
The second group of words which has a broken handle, also describes the umbrella and
so does the work of an Adjective. But because it contains a Subject and a Predicate of its
own, it is called an Adjective Clause.
Defination:- An Adjective Clause is a group of words which contains a Subject and a Predicate
of its own, and does the work of an Adjective.
