Relative pronouns and relative clauses

Level: beginner

The relative pronouns are:

Subject Object Possessive
who who/whom whose
which which whose
that that -

We use relative pronouns to introduce relative clauses. Relative clauses tell us more about people and things:

Lord Thompson, who is 76, has just retired.
This is the house which Jack built.
Marie Curie is the woman that discovered radium.

We use:

  • who and whom for people
  • which for things
  • that for people or things.

Two kinds of relative clause

There are two kinds of relative clause:

1.  We use relative clauses to make clear which person or thing we are talking about:

Marie Curie is the woman who discovered radium.
This is the house which Jack built.

In this kind of relative clause, we can use that instead of who or which:

Marie Curie is the woman that discovered radium.
This is the house that Jack built.

We can leave out the pronoun if it is the object of the relative clause:

This is the house that Jack built. (that is the object of built)

Relative pronouns 2

Be careful!

The relative pronoun is the subject/object of the relative clause, so we do not repeat the subject/object:

Marie Curie is the woman who she discovered radium.
(who is the subject of discovered, so we don't need she)

This is the house that Jack built it.
(that is the object of built, so we don't need it)

2.  We also use relative clauses to give more information about a person, thing or situation:

Lord Thompson, who is 76, has just retired.
We had fish and chips, which I always enjoy.
I met Rebecca in town yesterday, which was a nice surprise.

With this kind of relative clause, we use commas (,) to separate it from the rest of the sentence.

Be careful!

In this kind of relative clause, we cannot use that:

Lord Thompson, who is 76, has just retired.
(NOT Lord Thompson, that is 76, has just retired.)

and we cannot leave out the pronoun:

We had fish and chips, which I always enjoy.
(NOT We had fish and chips, I always enjoy.)

whose and whom

We use whose as the possessive form of who:

This is George, whose brother went to school with me.

We sometimes use whom as the object of a verb or preposition:

This is George, whom you met at our house last year.
(whom is the object of met)

This is George’s brother, with whom I went to school.
(whom is the object of with)

but nowadays we normally use who:

This is George, who you met at our house last year.
This is George’s brother, who I went to school with.

Relative pronouns with prepositions

When who(m) or which have a preposition, the preposition can come at the beginning of the clause:

I had an uncle in Germany, from who(m) I inherited a bit of money.
We bought a chainsaw, with which we cut up all the wood.

or at the end of the clause:

I had an uncle in Germany, who(m) I inherited a bit of money from.
We bought a chainsaw, which we cut all the wood up with.

But when that has a preposition, the preposition always comes at the end:

I didn't know the uncle that I inherited the money from.
We can't find the chainsaw that we cut all the wood up with.

when and where

We can use when with times and where with places to make it clear which time or place we are talking about:

England won the World Cup in 1966. It was the year when we got married.
I remember my twentieth birthday. It was the day when the tsunami happened.

Do you remember the place where we caught the train?
Stratford-upon-Avon is the town where Shakespeare was born.

We can leave out when:

England won the World Cup in 1966. It was the year we got married.
I remember my twentieth birthday. It was the day the tsunami happened.

We often use quantifiers and numbers with relative pronouns: 

all of which/whom most of which/whom many of which/whom
lots of which/whom a few of which/whom none of which/whom
one of which/whom two of which/whom etc.

She has three brothers, two of whom are in the army.
I read three books last week, one of which I really enjoyed.
There were some good programmes on the radio, none of which I listened to.

Hello. Which relative is correct in the following sentence? Why?
1- This is the best which he can do for you.
2- This is the best that he can do for you.
Thank you.

Hello Ahmed Imam,

Although both are grammatically possible, I think that is the natural choice here. We tend not to use who or which in constructions such as this, where the noun is omitted (the best thing).

 

That said, I think the majority of speakers would omit the relative pronoun altogether: This is the best he can do for you.

Hello. Is the following sentence correct? I can't understand it. What is its structure? How can I divide it into 2 simple sentences?

"That the rate of educated women has doubled since 1970s is related to their education."

Thank you.

Hello Ahmed Imam,

That sentence is a little odd. I'd suggest changing the beginning to 'The fact that the rate ...'. That would make it grammatically correct, but the logic appears circular to me.

All the best,

Hello!
I've been thinking about this sentence a lot: "Lily and her dogs, ... go out for a walk everyday, haven't had time to do that recently.
It's supposed to be a "that" to be filled in the blank if it was a defining relative clause. However, it's a non-defining one thus a "that" cannot be used here.
So please help me with this. Thank you so much!

Hi hoando124,

I would use who here, as Lily is a person. :)

Hello!

How can we differenciate on which from whose?

Thanks!

Hello Isa,

'whose' always includes the idea of possession, and usually the possessor is a person, animal or organisation (which is composed of people).

'which', on the other hand, refers to an object or idea, but doesn't include the idea of possession or a person that possesses something.

Does that help? If you have a specific sentence you would like to ask us about, please feel free to do that.

All the best,

Hello,
thanks for the content!
I don't know whether this has been stated before: I just wanted to let you know that Lagos isn't the capital of Nigeria (task 3).

Hello Imho,

Thanks very much for telling us about this mistake! I've just fixed it, though it may take a few hours for the change to appear on the site.

Best wishes,

Kirk
