1. RELATIVE PRONOUNS DEFINING RELATIVE CLAUSES NON-DEFINING RELATIVE CLAUSES

2. When we want to give extra information about the subject or the object of a sentence we need to add extra clauses. These clauses are often added on, or put inside a sentence and are introduced by relative pronouns. These relative pronouns help to make clear exactly what, where or who the extra information is referring to.

3. RELATIVE PRONOUNS match
Who (that)
Which (that)
When
Where
Whose
Why
Possession
Place

Things & Ideas

5. Remember
“that” is used instead of who and which when we are speaking or writing informally.
In the past WHOM was often used as the object of a relative clause, but today WHO is more normally used.

6. Which/who/that/where clauses
The relative pronouns are used in place of he, she, it or they to join two sentences together:
Subject relative clauses:
They were three friends. They often talked about setting up a business.
They were three friends who/that often talked about setting up a business.

7. 2) Object relative clauses:
They approached a number of venture capitalists. They thought they would be interested.
They approached a number of venture capitalists who/that they thought would be interested.
3) Relative clauses with where:
The company bought a bottle plant in the UK. They could manufacture the drinks there.
The company bought a bottle plant in the UK where they could manufacture the drinks.

14. Defining relative clauses
The defining relative clause identifies and defines the thing/place/person/reason or time talked about.
It is necessary for the meaning:
- Example: He’s the man (who that) I met on the plane.
Commas are not used
You can omit (who) when the verbs in the main clause and the relative clause have a different subject.
“that” (instead of which) can only be used for people and things in defining relative clauses. (NOT non-defining)

15. When can you omit (leave out) the pronoun?
When the relative pronoun (who/which/that) is the object of the relative clause and is followed by a noun or a pronoun, then it can be omitted.
Example: The woman (who) you saw yesterday has just been promoted. (different subject)
But if the pronoun is the subject of the relative pronoun and so followed by a verb, we must keep it.
Example: The technician who came to fix the computer said we needed a new one. (same subject)
You can omit the relative pronoun when the verbs in the main clause and in the relative clause have a different subject.

16. example Example: He’s the man (who/that) I met on the plane.
You can omit who.
The subject of met is I, (not he) so it’s not necessary to put who. (=two different subjects)

17. Other examples: Defining
The summer is the time when we sell more of our products
The weather is (the reason) why I decided to come home early.
This is the street where I was born.
That’s the boy whose father plays for Real Madrid.
It’s a book which tells you how to do marketing

Rain……is polluted with chemicals from factories is called acid rain.
A farmer ……farm is organic does not use harmful chemicals to grow food.
The greenhouse effect is something …….happens when the sun’s heat is trapped close to the Earth by pollution.

22. NON-defining relative clauses
The relative pronoun can’t be omitted
In these sentences you can’t use that instead of who/which
The clause is written inside commas:
Example: The regional sales manager, who is a close friend of mine, has just been given a salary rise of 20%.
The information inside commas can be removed without the sentence losing its meaning. (the sentence makes sense without it)
