DEFINING (no commas)
Relative clauses add extra information to a sentence by defining a noun. They are usually divided into two types –
defining relative clauses and
non-defining relative clauses.
Defining relative clauses
We use defining relative clauses to
give essential information about someone or something – information that
we need in order to understand what or who is being referred to. A
defining relative clause usually comes immediately after the noun it
describes.
We usually use a relative pronoun (e.g. who, whom, that, which, whose, where, when, why) to introduce a defining relative clause. In the examples, the relative clause is in bold, and the person or thing being referred to is underlined:
1.-They’re the people who/that want to buy our house.
2.-Here are some houses which/that have been affected by the flood.
3.-They should give the money to somebody who/that they think needs the treatment most.
4.-The actress is now playing a woman whose son was killed in the First World War.
5.-
This is the town where I studied my university degree.
6.-The day when/that the concert takes place is Saturday.
7.-This is the reason why I didn't invite him to the party.
We can leave out the relative pronoun when it is the object of the verb:
They’re the people (who/that) she met at Jon’s party.
This is the book (which/that) I borrowed from the library.
The relative pronoun cannot be omitted when it isthe subject of the verb:
This is the boy who/that helped us with our luggage.
This is the boy (who/that) we meet at the party.
IMPORTANT: Where and whose are never omitted.
It is important to use the possessive WHOSE correctly:
Example: He's the man whose car was stolen last week.
They were sure to visit the town whose location
NON-DEFINING
Look at this sentence.
- My grandfather, who is 87, goes swimming every day.
‘who is 87’ is a
non-defining relative clause. It adds extra information to the sentence. If we take the clause out of the sentence, the sentence still has the same meaning.
Look at some more examples.
- Tom Carter, who plays the leading role in this film, is a great actor.
- My eldest son, whose work takes him all over the world, is in Hong Kong at the moment.
- The car, which can reach speeds of over 300km/ph, costs over $500,000.
- Cáceres, where most of my students were born, is a wonderful town.
Non-defining relative clauses add extra information to sentences.
Defining or non-defining?
Remember that
defining relative clauses are used to add important information. The sentence would have a different meaning without the
defining relative clause.
- I’m going to wear the skirt that I bought in London. The defining relative clause tells us which skirt.
- This skirt, which is a lovely dark blue colour, only cost £10. The non-defining relative clause doesn’t tell us which skirt – it gives us more information about the skirt.
Non-defining relative clauses use WHO, WHICH, WHERE, WHEN, WHOSE, but they but they CAN’T use THAT.
The relative pronoun can never be omitted in a non-defining relative clause.
The film, that stars Tom Carter, is released on Friday.- The film, which stars Tom Carter, is released on Friday
Non-defining relative clauses are more often used in written English than in spoken English. You can tell that a clause is non-defining because it is separated by commas at each end of the clause.
