An adjective clause is a dependent clause that modifies a noun or pronoun. It functions like an adjective, providing more information about the noun or pronoun it modifies.
Here's the breakdown:
* Adjective Clause: A group of words containing a subject and a verb that functions as an adjective.
* Introductory Word: A word that begins a sentence, phrase, or clause.
While an adjective clause may begin with a relative pronoun (who, whom, whose, which, that), this is not an "introductory word" in the traditional sense. It's part of the clause itself, acting as the subject or object of the clause.
Examples:
* The man who lives next door is a doctor. (The adjective clause "who lives next door" modifies the noun "man".)
* The book that I read yesterday was interesting. (The adjective clause "that I read yesterday" modifies the noun "book".)
In summary: Adjective clauses are introduced by relative pronouns, which are essential parts of the clause, not introductory words.
