# Relative pronouns and relative clauses

Learn about relative pronouns and relative clauses and do the exercises to practise using them.

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 1

GapFillDragAndDrop_MTU4ODQ=

Relative pronouns 2

GapFillTyping_MTU4ODY=

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.)

Relative pronouns 3

GapFillDragAndDrop_MTU4OTE=

Relative pronouns 4

GapFillTyping_MTU4OTI=

Level: intermediate

## 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 5

MultipleSelection_MTU4OTM=

## 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.

Relative pronouns 6

GapFillTyping_MTU4OTQ=

## 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 I'm a newbie to Grammar. How would you explain past-tense to an object - so... Yesterday I was... then referring to a park bench... a local homeless man usually occupied, either sitting or lying down, but today it was empty. How would you write today it was empty, whilst keeping past tense? Thanks.

Hello jpreston,

I'm afraid I don't understand your question. The phrase 'today it was empty' is perfectly fine and uses a past tense. You seem to be asking how you would change something which does not need changing to fit your criteria.

Hello, Is it right to say that relative pronouns act like an adjective, hence, we can find it always after the noun\subject they describe in a sentence?

Submitted by Peter M. on Thu, 31/10/2019 - 08:33

In reply to by orian

Hello orian,

It's not the relative pronoun which acts as an adjective, but rather the whole of the relative clause. Relative clauses can describe the nouns which precede them, or can describe the whole sentence:

The kettle, which was an old antique, made a loud whistling sound.

The relative clause describes 'kettle'.

We put the relative clause immediately after the noun, as you say.

The kettle began to melt, which none of us had expected!

The relative clause describes the whole sentence, giving the speaker's reaction to it.

Hi I would like to make clear that in all sentences where I have to fill "who" or "which" I can replace by "that" Or there are cases where I can only use "that" Thank u

Submitted by Kirk Moore on Thu, 17/10/2019 - 06:41

In reply to by Didi

Hello Didi

I'm afraid it's not quite that simple. For one thing, 'who' is not always a relative pronoun (e.g. 'Who invented the telephone?). Also, in the first kind of relative clauses explained above -- these are sometimes called 'defining relative clauses' -- 'who' can always be replaced by 'that', though I would recommend you learn and practise both. But in the second kind of relative clauses explained above -- these are sometimes called 'non-defining relative clauses' -- only 'who' is correct when we are speaking about a person.

The case is the same for 'which': it is also used in questions (e.g. 'Which film did you see?') and 'that' cannot replace it in non-defining relative clauses, when we use 'which' to give more information -- see for example the sentence 'We had fish and chips, which I always enjoy' above.

Hello. Could you please help me? Which relative pronoun is correct or both? 1- All we want to know is the truth about whom is to blame for this fatal error. 2- All we want to know is the truth about who is to blame for this fatal error. Some books of English say that after prepositions we must use "whom" not "who". I am really confused. Thank you. thank you.

Hello Ahmed Imam

It's true that object forms are used after prepositions, but I would suggest using 'who' here. This is because 'who/whom' is a bit of a special case -- 'whom' has mostly disappeared in most informal, and even many formal, situations nowadays.

There's also the fact that there are situations where both forms are possible. In this case, 'who' or 'whom' is not simply the object of 'about' -- instead it is the head of the phrase 'who/whom is to blame', and it is this phrase that is the object of 'about'. Whether it's correct to use 'who' or 'whom' at the head of such a phrase is a question of style as far as I know.

Hope this helps.

Greetings, in the relative pronouns 6, example 6, shouldn't it be "after" not "from"? Doesn't it state that the poor grandma literally passed on the eyes? Regards

Submitted by Kirk Moore on Mon, 16/09/2019 - 22:21

In reply to by Klecia

Hello Klecia

Perhaps in a very specific context this would express what you mean, but in general it is not literal but rather figurative. 'after' would not be correct as a substitute for 'from', but perhaps you're thinking of the phrasal verb 'to take after', which means that a person is similar to another one, usually family, e.g. 'When people see my grandmother's green eyes, they say I take after her'.

Thank you so much! I didn't know how to phrase my question, so I wrote the sentence itself. Is there a rule on singular and plural verbs with "who"? I have often heard phrases like "For those of you, who don't know..." and such, so I thought that the verb should be suitable for something that the "who" refers to. But my English teacher said to me that the verbs in my phrase should be singular. My Grammarly app told me that both options are correct, so I was confused. I couldn't find a rule for that, this topic is the closest I could find. In the comment section I found some similar questions, but still asked for you opinion, just to be sure. Thank you for the help!

What is the main difference between adjective clause and relative clause? Our teacher told us that it has difference?

Hello Hayatullah,

In most grammatical descriptions of English relative clause and adjectival clause are alternative names for the same thing: a dependent clause which describes a noun or noun phrase.

Hi, In the following sentences, is the use of the demonstrative pronoun "this" grammatically correct and/or acceptable in exams such as IELTS? I hold a bachelor's degree. That is the reason why I was eligible to apply for the job. I ask this question as I read in some of the websites related to grammar that the pronouns "which", "that", "this" cannot refer to a group of words, such as a sentence.

Hi Peter, Good day! I am just newly registered on this page. I have come across this website while trying to look for an answer to the grammatical structure of relative/ adjective clauses that has put me in a state of quandary. My question is, "is the tense in a relative/adjective clause independent of the tense in the main clause all the time?" If not, could you please provide me example of a relative clause that depends it tense on the tense of the main clause. Example: The woman (whom) you met a week ago is my cousin. The woman who will call you tomorrow is my secretary. This is the house where the woman was murdered. The boy who was bullying our kid when he was in elementary is the president's son. Thank you!

Hello mik0303

As far as I can think, the times of the two clauses are independent. Perhaps there could be particular situation in which they have to be the same, but if such an example exists, it would generally be clear from the context.

Does that make sense? If you find a counterexample of this, please do share it -- this kind of question is very difficult to answer, because there are so many possibilities!

Hello Sir, I don't understand why you put : who or that in the sentence below : She's the only person ............... really understands me. I can't see the preposition, in which the rules of grammar above can find it.

In reply to by Momocompanyman

Hi Momocompanyman,

There is no preposition in this sentence. In fact, if there was a preposition in the sentence, the relative pronoun would have to be 'which' instead of 'who' or 'that'. This sentence is a combination of:

1. She is the only person.
2. She understands me.

Since the antecedent of the pronoun is a person that is the subject of the verb 'understands', we can use 'who' or 'that'.

Best wishes,

Hello, The sentence below gets me confused. "Fewer than one in 100,000 people have died in combat per year since 2000—one-sixth the rate between 1950 and 2000, and one-fiftieth of that between 1900 and 1950." I understand those rates in the sentence (one in each 100.000 people since 2000,one in each 6 people between 1950 and 2000,one in each 15 people between 1900-1950) respectively. Is this true? Can we say "one-sixth the rate(which is) between 1950 and 2000" and "one-fiftieth of that(which is) between 1900 and 1950."? Thank you for your help.

Submitted by Peter M. on Wed, 14/11/2018 - 07:19

In reply to by Goktug123

Hello Goktug123,

There are three rates in this sentence.

(1) fewer than 1 in 100,000

(2) the rate between 1950 and 2000, which was six times higher than the rate in (1)

(3) the rate between 1900 and 1950, which was fifty times higher than the rate in (1)

In other words, 'one-sixth' does not mean 'one in six', but rather tells us that the rate was 6 in 100,000 between 1950 and 2000.

'One fiftieth' does not mean 'one in fifty', but rather tells us that the rate was 50 in 100,000 between 1900 and 1950.

We would not use 'which' here. You can say 'the rate between 1950 and 2000', 'the rate of (the period) 1950-2000' or 'the 1950-2000 rate'.

Please note that we generally do not answer questions about sentences from elsewhere. We're happy to explain examples from our own pages or try to answer more general questions about the language, but answering questions from other sources is something we rarely do as, first, we have limited time and, second, we do not know the source and the author's intention, making interpretation difficult.

Hello rajusikar,

'What' is not a relative pronoun.

You can read a good summary of English relative pronouns and their use on this page:

https://dictionary.cambridge.org/grammar/british-grammar/pronouns/relative-pronouns

It is possible for adverbial clauses to function as relative clauses. These can be introduced with various adverbs, the most common of which are 'where', 'when', why', 'whenever' and 'wherever'. You can see some examples at the bottom of this page:

Hi Mr Peter M, thanks for your response. Maybe I wasn't too clear in my question. In the sentence below, will it be grammatically correct to use "was"? - One of the boys who was/were having tea in the cafe witnessed the incident. "One of the boys" refers to one of many boys, so we would usually say that "One of the boys was.....". However, when a pronoun "who" is inserted into the sentence, is it true that the tense has to agree with the antecedent before the pronoun (in this case, the antecedent is "boys")? If so, it is therefore grammatically correct that only "were" has to be used? Thanks for your patience.

Hi Saffron,

I think the plural verb is the correct option here, assuming that there are many boys having tea and we are talking about one of them.

If only one boy is having tea then we have two choices. We could use a defining relative clause and not the phrase 'one of':

The boy who was having tea...

Alternatively, we could use a non-defining relative clause:

One of the boys, who was having tea, witnessed...

This would require commas around the clause, as above.
