What Are Adjective Clauses?

An adjective clause is a group of words that describes a noun. It gives more information about a person, place, thing, or idea.

It begins with words like who, whom, whose, which, that, when, or where.

Adjective clauses come right after the noun they describe.
For example:
The man who lives next door is a doctor.
Here, “who lives next door” gives more information about “the man.”

Some adjective clauses are essential to the sentence. Others just add extra detail.

10 FAQs on Adjective Clauses

1. What is an adjective clause?
An adjective clause is a group of words that describes a noun, acting like an adjective.

2. How is an adjective clause different from an adjective?
An adjective is a single word (like beautiful), while an adjective clause has a subject and a verb.

3. What are common words that start adjective clauses?
Words like who, which, that, whose, where, and when.

4. Can adjective clauses come at the beginning of a sentence?
No, they usually follow the noun they describe.

5. What’s the difference between “who” and “whom” in adjective clauses?
Use who as the subject, and whom as the object, though whom is often dropped in casual English.

Not always. Use commas for non-defining clauses, and no comma for defining ones.

7. What is a defining adjective clause?
It gives essential information. Example: “The man who called is my boss.”

8. What is a non-defining adjective clause?
It adds extra information. Example: “My brother, who lives in Canada, is visiting.”

Yes, sometimes it’s possible, especially in informal speech: “The book (that) I read was good.”

10. How can I help students practice adjective clauses in real life?
Use games, interviews, or ask students to describe people, places, or things using adjective clauses.
