1. Introduction - Relative clauses with
who, which and that
Emma: / saw Natalie the other day.
Melanie: Natalie? The girl who plays the
piano?
Emma: No, that's Natasha. Natalie is the
student who dropped out of college, the one
who never did any studying. She's working in
Davidson's now, the shop that sells very
expensive clothes.

2. The relative clauses in this conversation
identify which person or thing we are
talking about. The clause who plays the
piano tells us which girl Melanie means.
The clause that sells very expensive
clothes tells us which shop Emma means.

3. Sometimes we can use an adjective or a phrase
to identify someone or something.
Adjective: the tall girl the new student
the red car
Phrase: the man in the suit the shop on
the corner the woman with red hair
But when we need a longer explanation, we
can use a relative clause.
Relative clause: the woman who gets up early
the car that broke down

4. Who, which and that
The relative pronouns who, which and that go after the
noun and at the beginning of the relative clause.
Who refers to people.
Nick is the man who owns that enormous dog. I don't
like people who tell jokes all the time.
The little girl who sat next to me on the coach ate
sweets the whole way.
Sarah is pretty annoyed with the person who stole
her mobile phone. We
can also use that, but it is less usual.
Jake is the man that plays the guitar.
The woman that lived here before us is a romantic
novelist.

5. That and which refer to things. That is more
usual than which, especially in conversation.
The car that won the race looked very
futuristic, didn't it? They've recaptured all the
animals that escaped from the zoo. The
children saw the actual spacecraft that landed
on the moon.

6. Which can be a little formal.
There are several restaurants which do
Sunday lunches. Is Zedco the company
which was taken over last year?
