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 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)

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.~~)

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 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.

You use commas, whenever you see Spiderman in the TV. Its important that it has to be Spiderman and not any other hero. Loko

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?

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

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

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'.

Hello Ngeata,

The sentence is correct grammatically.

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.

1. There are several different credit types you may have on your account depending on certain actions you perform on the website. 2. Pay in many while-collar job has been stagnating relative to inflation. Why we use "depending" and "relative" in these sentences? are they reduced relative clauses? Thank you in advanced.

Hi Sir, Is my sentence correct? The era in which people spend most of their time playing gadget is the dangerous era for our children. Can I use 'when' instead of 'in which'? Are my words appropriate in the case? Thank you,sir

Hello Risa warysha

Yes, it's correct to use 'when' instead of 'in which' here, though personally I would use 'in which' -- it just sounds better to me. But 'when' is fine.

'playing gadget' should be 'playing with gadgets'.

Hello. "the place which you can't go is not yours" "the place which you can't go doesn't belong you" "the place what you can't go is not yours" Are there some problems with these sentences? Could you comment their meanings and as grammars, please? Or May you offer some different sentences near their meanings? Thank you very much. Kind Regards..

Hello redream

I wouldn't use the word 'which' in either of the first two sentences and in the second one the word 'to' needs to be used before 'you'. 'what' is not correct in the third sentence.

I'm afraid we don't normally provide detailed explanations of texts that don't come from our site, as it takes quite a lot of time to do it well. If you have a more specific question, please free to ask us, however.

She had two sons, both of ___ killed in the war. A. whom B. them C. which D. whose Which of these are correct, and why?

Hello Kieu123

B and C could work here, though there is a difference in meaning. B (which is short for 'both of whom were killed in the war') means the two sons were killed in war and C means the two boys killed other people in the war.

The class which I joined was very interesting. The class where I joined was very interesting. The class that I joined was very interesting. Which sentence is grammatically wrong? Thanks

Hello jafari2002

The second sentence is not correct. A class is not a place and so the relative pronoun 'where' is not appropriate there.

Hello, When we write "we live in an era when/where every actions and conversations are monitored through CCTV cameras and smartphones" Which relative pronoun is correct between when and where? "When" sounds unatural to me but I can't explain why for this particular word...

Hello Fareyal 'when' is better than 'where' here, since an era is a period of time and not a place. 'in which' is also a good option here, though it's a little more formal than 'when' -- depending on the situation, this might be more or less appropriate. All the best Kirk The LearnEnglish Team

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.

Hello sam61 Yes, you have used 'that' correctly in this series of sentences. It is also possible to say 'this' in this case. The three pronouns you mention are quite versatile and can be used to refer to the ideas expressed in phrases, sentences or even multiple related sentences. All the best Kirk The LearnEnglish Team

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!

Hi,I think that in this sentence: This is the house where I live, the second tense depends on the first one.

It includes various workshops and games, which students can learn and stimulate their mind. Or which help students learn and stimulate their mind? Or can I say with which / in which instead?

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.

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:

She is the only person.
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.

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.

Is what a relative pronoun? How many relative adverbs are there in English? Plz tell me sir.

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.

Peter

The LearnEnglish Team

Hi, are the following correct? 1) One of the boys has a pet dog. 2) One of the boys who were having tea in the cafe witnessed the incident.

Hi Saffron,

Yes, those sentences look perfectly fine to me.

Thank you, Mr Peter M. So pronouns like 'who', 'that' and 'which' become singular or plural according to the noun directly in front of them?

Hello Saffron,

Those pronouns can all refer to singular or plural nouns.
