What is an adjective clause and how is it used to modify nouns?

An adjective clause is a dependent clause that functions as an adjective in a sentence. It is used to modify or describe a noun or pronoun by providing additional information about it. Adjective clauses typically begin with relative pronouns (such as who, whom, whose, which, or that) or relative adverbs (such as when, where, or why). These clauses can provide details about the noun they modify, such as identifying or defining it, giving more information about its characteristics, or specifying its location or time.
