1. Relative Clauses

2. What are relative clauses?
Subordinate clauses which allow us to add information about people or things we are talking to, without a need to repeat the name
e.g. That is the house. The house was built on the main road.
That is the house which was built on the main road.

3. STRUCTURE [Principal (relative clause) clause]
People who work hard have got a successful life
[Principal (relative clause) clause]
In many of the cases, the relative pronoun works as the subject of the relative clause. In these cases we CAN’T omit the relative pronoun!
She is the girl who went to the cinema
In other cases, the pronoun works as the object of the relative clause, then we CAN omit the relative pronoun!
She is the girl who you want to meet

4. TYPES OF RELATIVE CLAUSES
DEFINING
It was my mum who called
NON-DEFINING
Barcelona, where I studied, is a very popular city.

5. DEFINING RELATIVE CLAUSES
They give essential information about their antecedent and without them, the meaning will be incompleted. That is why you write them without commas. (oracions especificatives)
The computer which we bought is very expensive
The man who is coming will bring us the present

6. The relative pronoun you use depends on the thing you're talking about
The relative pronoun you use depends on the thing you're talking about. Generally speaking, the most basic ones are these:
for people
…who/that/whom
for things
…which/that
for places
…where
for reasons
…why
for times
…when
For possesions
…Whose

7. Ok… Lets review how we choose relative pronouns.
Who is a subject or object pronoun for people
Example - I told you about the woman who lives next door.
Which is a subject or object pronoun for animals, buildings, and things Example - Do you see the cat which is lying on the roof?
Which also refers to a whole sentence
Example - He couldn’t read which surprised me.
Whose is a possession for people animals and things
Example - Do you know the boy whose mother is a nurse?
Whom is an object pronoun for people.
Example - I was invited by the professor whom I met at the conference.
That is a subject or object pronoun for people, animals and things in defining relative clauses (who or which are also possible)
Example - I don’t like the table that stands in the kitchen.

8. Remember:
Use WHO to refer to people and WHICH to refer to animals, things, …
“THAT” can replace WHO and WHICH in Defining Relative Clauses : Did you know the girl WHO/THAT came to the party yesterday? The book WHICH/THAT I’m reading is very interesting.

9. WHOM
is used instead of WHO in Formal Speech when it is the Object of the Relative Clause or after a preposition:
- I couldn’t talk to a friend + I called him last night: I couldn’t talk to the friend WHOM I called last night.
- I don’t know the student + The teacher was shouting at the student: I don’t know the student at WHOM the teacher was shouting.

10. WHEN (THAT) Relatives: shows Time:
- I will never forget the day + I met my best friend that day: I’ll never forget the day (WHEN/THAT) I met my best friend.
(WHEN can also be omitted in Defining Relative Clauses).

11. WHERE refers to Places:
-This is the hotel + We are staying at the hotel next weekend:
This is the hotel WHERE we are staying next weekend.
- The city is interesting + my sister is living in the city:
The city WHERE my sister is living is interesting.

12. WHOSE
shows Possession and it replaces a Possessive adjective or an ’s possessive:
- The man was crying + His house was on fire:
The man WHOSE house was on fire was crying.
- Have you met the people? + Their son is moving to Washington: Have you met the people WHOSE son is moving to Washington?

13. WHAT Is used in DR clauses to mean the thing that
Has she told you what’s worrying her?
What you need is love

14. WHY Can be used in DR clauses to mean the reason why
I don’t know why we are arguing

15. EXERCISE

The reason………… he gave us for delay frustrated us all
Sunday is the day ……….. We usually go shopping
Spring and autumn are the seasons……. I like best

16. EXERCISE

The reason (WHICH/THAT) he gave us for delay frustrated us all
Sunday is the day (WHEN/THAT/ON WHICH)We usually go shopping
Spring and autumn are the seasons (WHICH/THAT) I like best
Don’t clean the room WHEREmy soon is studying
I like the house WHICH/THAThas a large garde

17. NON-DEFINING RELATIVE CLAUSES
Extra information
The principal sentence keeps the meaning if we omit them.
They go between commas
Examples:
My teacher, who studied with my father, is not going to come today.
Sabadell, where I was born, is a city near Barcelona.
She, who is Canadian, works as a lawyer.

18. Defining or Non-Defining?
Remember:
Defining Relative Clauses:
Don’t take commas.
“That” can replace Who, Which and When.
- You can omit Who, Which, When and That when they are not the Subject of the Relative Clause.
Non-Defining Relative Clauses:
Go between commas.
You can’t use “That”.
You can’t omit the Relatives.
Defining or Non-Defining?

19. FORMAL AND INFORMAL STRUCTURE
If the verb in the relative clause is followed by a preposition ON, TO, FOR, WITH, then…
there are 2 ways to form a relative clause:

20. FORMAL The woman to whom I talked was very nice.
She is the woman for whom they have been looking.
- The preposition becomes before the relative pronoun.
- We use the relative pronoun WHOM instead of WHO

21. INFORMAL The woman (WHO) I talked to was very nice.
She is a very nice woman (WHO) you can trust in
The preposition comes after the verb.
