21.16 Relative Pronouns and Clauses

An adjective clause gives information about a preceding noun in a sentence. Look at the following examples.

The car that Richie was driving was yellow.

Des Moines, where I live, is in Iowa.

Mr. Creeter, whose brother I know, is the new math teacher.

Like many other adjective clauses, these begin with a relative adjective (which, who, whom, whose, that) or a relative adverb (when or where). When you use a relative clause to describe a noun, make sure to begin it with one of the seven relative adjectives and adverbs listed in the previous sentence.
