Adjective Clause

DEFINITION

An adjective clause is simply a group of words with a subject and a verb that provide a description. The clause starts with a pronoun such as who, whom, that, or which or an adverb such as when, where and why.

An adjective clause is a dependent clause that modifies a noun.  It is possible to combine the following two sentences to form one sentence containing an adjective clause: 

       

The children are going to visit the museum.
They are on the bus.

The children who are on the bus are going to visit the museum.

In the sentence above, there are two other ways to write the sentence correctly using the second sentence as the adjective clause. 

•        The children that are on the bus are going to visit the museum.

•        The children       on the bus       are going to visit the museum.
