Lesson Eight

Adjective Clauses

An adjective clause is a clause that describes a word or a group of words in another clause. Adjective clauses are often part of a complex sentence.

Adjective clauses use that, who, whom, and which to begin the clause:

She’s the person who gave me the idea.


She’s the person that gave me the idea.

In both sentences, the person is described by…

She gave me the idea.

…but use that or who in place of "she."


Here are some examples:

This student who comes from Japan is a very nice person.

female student

The highway that George travels on every day is usually very crowded during rush hour.


George is a man who likes to eat a lot of watermelon.


mean eating watermelon
