ADJECTIVE CLAUSES 1

Grammar review An adjective clause describes a noun, the same way a single adjective would — it just uses a full clause to do it. You may also see this same structure called a relative clause in other grammar books and exercises; both names refer to exactly the same thing. Combining two sentences into one with an adjective clause makes writing tighter and more natural.

Who — for people, subject of the clause: The man who called is my neighbor.
Which — for things or animals: The book which I read was long.
That — for people, things, or animals (informal, common in speech): The dog that barked was loud.
Whose — shows possession, for people or things: The man whose car was stolen called the police.

How to combine: find the noun the two sentences share, then replace it in the second sentence with the correct relative pronoun, and slot that clause right after the noun in the first sentence.
