# 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

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)

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

Relative pronouns 4

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

## 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

## 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.

one or other means one of two people or things, when it does not matter which you are referring to - Would the formal version be "it does not matter to which you are referring" She sits on a “reputation committee”, a subgroup of the company’s executive committee, which is chaired by the chief executive. - does "which" refer to "reputation committee" or the "executive committee"? The government has received more than 2,000 submissions, mostly opposing the proposal. - As I understand the use of relative clauses and participial clauses, when we are referring to the noun which is at the end of a sentence, it would be better to use relative clauses rather than participal clauses, which tend to refer to the whole of the previous sentence. Since "most opposing the proposal" refers to the submissions, would it be better to say "which mostly oppose the proposal". Thanks for your help teachers.

Hi Anisha00329,

1. Yes – that would be a very formal way to say one or other. But, note that one or other isn't marked for any particular style, so it's perfectly fine to use it in formal writing or speaking. Also, it's just a phrase (i.e. part of a sentence), while your suggestion is a full sentence.
2. It refers to reputation committee. But, if you deleted the comma after executive committee, then it would refer to executive committee. So, the comma makes a small but important difference!
3. Yes! It would be better to use the relative clause here, for the reason that you said.

I hope that helps!

Best wishes,

Jonathan

Hello thank for sharing this material. My question is, according to Cambridge Objective Advanced preposition cannot be used before "who" but "whom" can be used. If we want to use preposition with "who", it is supposed to be at the end of the clause. But here it says, who/whom can be used with the same way. Could you please explain that a little further? Many thanks in advance.

Hi Natavan Gojayeva,

Yes, in moden usage of British English, who is often used instead of whom. Here are some examples to compare:

1. Whom should I talk to?
2. To whom should I talk?
3. Who should I talk to?

1 and 2 are traditionally regarded as correct. In some varieties of English, it's not recommended to end a sentence with a preposition, so 1 and 3 would be regarded as incorrect. Version 3 uses who instead of whom (which is traditionally incorrect), but this would be the most commonly used version (in British English, at least) and few people would consider it an error. Speakers would only use 1 and 2 if they were making a special effort to speak correctly.

As you can see, it's a bit complicated :)

Best wishes,

Jonathan

Hello thank you very much for your explanation. But my confusion is, here in the explanation "from who/whom" is correct to use. But in advanced cambridge it say preposition+whom is correct otherwise preposition has to come after the clause if we use "who/that" E.g. She spoke to a professor that/who she is friendly with. She spoke to a professor with whom she is friendly. I hope I could explain. Thank in advance for taking time to read my post.

Hi Natavan Gojayeva,

OK, I see now. I agree with the Cambridge book you mentioned, and that is what is traditionally regarded as correct.

But, we can also consider how language is used in real life, which does not always follow what is traditionally regarded as correct. The examples above using who(m) are a description of what people actually say (in speaking, especially), even though it might be considered incorrect.

So, it's good to be aware of the "correct" forms if you are taking an exam, or writing or speaking in a situation where correctness is important. But in everyday, casual conversation, all the forms described above are acceptable.

I hope I've explained it more clearly now?

Best wishes,

Jonathan

"Lindsey plays field hockey now, but last year she was on the soccer team". The coordinating conjunction "but" in this sentence is meant to connect two main (independent) clauses, each of which should rightfully be able to stand on its own given that they are main clauses. My question is that since second main (independent) clause "last year she was on the soccer team" uses a relative pronoun "she", which links to "Lindsey" in the first (main) independent clause, how can the second clause be considered a true (main) independent clause which can stand on its own? And if indeed for this reason the second clause can no longer be considered as a true (main) independent clause, then doesn't this mean the use of the coordination conjunction "but" is not justified since a coordinating conjunction's role is primarily to link two (main) independent clauses?

Hello magnuslin,

The pronoun she requires a referent but that does not mean that it cannot be used in an independent clause. The referent can be in a different sentence, even a sentence which another person said, or it can be something extra-linguistic such as a picture of a person which is visible to the speakers.

More fundamentally, a sentence does not have to make sense to be grammatical. You can create perfectly grammatical sentences which make no sense at all.

She is the best girl ... I have ever met Why the answer is that not whom

Whom is the object pronoun but is disappearing from use in modern English. Nowadays it is only required when it directly follows a preposition (so we say to whom, for whom and with whom rather than to who, for who and with who).

In other contexts, even if whom is grammartically possible, it can sound very unnatural. This is the case in your example. Whom is not grammatically incorrect, but it is not the normal choice in modern English and sounds rather unnatural.

Hi, When a relative clause is introduced with relative adverbs such as when, where and why, is the clause still considered a relative clause? or must relative clauses always be introduced by relative pronouns which refer to nouns (i.e. the relative clause introduced with a relative pronoun, serves to give more information about the noun that the relative clause modifies)? Also, when used this way, it seems that oxford lexico dictionary describes such "when, where or why", as relative adverbs...for example use of "when" in "Tuesday is the day when we have pizza". But it seems to me that "when" here is modifying day (a noun), so why is it that some people call "when" a relative adverb, while others see "when" here as an "adjective" since it modifies a noun (i.e. day)?

Submitted by Peter M. on Mon, 22/06/2020 - 07:52

Hi Tim,

Yes, the relative clause is still a relative clause. It is usually called an adverb relative clause.

You need to distinguish between the adverb (when, where, why) and the clause as a whole. The function of the adverb is to head the clause and act as a connector with the rest of the sentence. The function of the clause as a whole is adjectival, as you say. In other words, the relative adverb is part of an adjectival clause.

You can often replace the relative adverb with a preposition and a relative pronoun:

Tuesday is the day on which we have pizza.

Adverbs are perhaps the broadest category of word in English and sometimes the category is controversial for this reason, being seen as a catch-all category whose members have an extraordinary range of functions. You can see some of these under these links:

Why are relative clauses also called adjective clauses?

Hello Tim,

Relative clauses provide information about a noun (or noun phrase) so their function in the sentence is adjectival. That is why they are sometimes called adjective clauses.

Hello I have a question concerning the relative pronouns "who/whom". (who) is used as a subject of a verb and (whom) as an object of a verb or preposition. When I was doing an exercise about determining whether the relative pronoun a subject pronoun or object pronoun I found these sentences: 1. Do you know the girl who I danced with? 2. This is the man who Barbara visited in Scotland. I think they should normally be with (whom) not with (who). I know that it is used in spoken or informal language but what about formal or Academic English, is it correct to use (who) instead of (whom) when it functions as an object? thanks in advance!

Submitted by Kirk Moore on Fri, 12/06/2020 - 09:15

In reply to by Erwin Smith

Hello Erwin Smith

That's correct -- in informal situations, and even in some formal ones, people often use 'who' instead of 'whom'. There's quite a bit of variation in formal and academic writing and speaking -- sometimes you see or hear 'whom' and sometimes 'who'. It's difficult to give advice without knowing more about your situation, but you might perhaps use 'whom' in writing but 'who' in speaking.

All the best

I got confused whether or not there's a comma here: I have a friend (,) who collects stamp. I think "I have a friend." is grammatically correct and it can stand alone as a full sentence. Is the comma necessary? Thank you.

Hello heoquay193,

Although we don't have the context, I think it is clear that this is a defining relative clause (identifying which friend you have in mind) rather than a non-defining relative clause (providing extra but unnecessary information). Defining relative clauses are not separated by a commas, so no comma should be used.

I think these examples are like that: 1- A stunt person is someone who ''stands in'' for an actor during dangerous scenes. Defined 2- A computer-graphics supervisor who needs advanced technical knowledge often spends millions of dollars on computer graphics. Non-defined 3- A stagehand is the person who moves the sets of stage in a theater production. Defined 4- A movie producer who controls the budget decides how money will be spent. it is defined as well, because people do not know about this job. Am I right?

Hello Teachers I have a question which has been puzzled me a lot. When it it comes to the different now types, is there any difference between them? For example are common, proper, abstract collective or job titles like ''stagehand'' or ''computer-graphics supervise'' must always be defined on Non-defined? I will appreciate providing examples.

Hello Ahmed2020,

I think you're a little confused with the terminology here. Defining and non-defining in the context of this page refer to relative clauses, not to nouns. They describe particular grammatical constructions:

> defining relative clauses identify the particular item being described (more here)

> non-defining relative clauses give extra, non-essential information about the item being described (more here)

Hello. I'm not clear which of these two sentences is dramatically correct. 1. The works that involve person-to-person interactions... 2. The works that involves person-to-person interactions... Thank for your explanation in advance.

Hello Nguyen Quoc Cuong

The first one is grammatically correct: the verb 'involve' agrees with the plural noun 'works'. In 2, 'involves' would agree with the subject 'work', but not 'works'.

Hello Tamigorositt,

The sentences in the first example can be joined with who or that:

The person who/that you met wasn't Michael.

You could omit the relative pronoun:

The person you met wasn't Michael.

Your second example can be rewritten with a relative adverb, not a relative pronoun:

I can't remember the hotel where we stayed.

Hello GalaxyWolf-Dragon6786

There are different ways you could combine the first one:

Michael, who had a really loud voice, announced the results.
Michael, who announced the results, had a really loud voice.

For the second one I'd say 'The form with the best results won the cup, which was presented by Mr Cadogan.'

The first two are fine, but the third is a bit awkward. Different writers and editors also have different opinions about the use of dashes, so in general I'd avoid them if possible. Instead, I'd write something like 'A few 6th-grade students planned a party'.

The correct form is as follows:

Hello Niania,

The relative clause beginning which stretches... is a defining relative clause. It does not only add extra information to the sentence but actually defines the noun before it. In other words, it answers the question 'Which range?'

In this sentence, when is a subordinating conjunction. It introduces a dependent clause which has an adverbial function, giving us more information about the action in the main clause.

Hello! Someone asked me which of these sentences is correct: For you who dare to dream. For you who dares to dream. For you who are bold. For you who is bold. I thought it should depend on whether 'you' referred to one or many people. But when I looked for examples on this sentence pattern, I only got more confused! What if the sentence started with "It is you..."? It is you who dare to dream. It is you who dares to dream. It is you who are wrong. It is you who is wrong. Would really appreciate some tips on how to figure these out. Thanks!

Hello zhouyoumin,

You are correct that the question is whether or not 'you' refers to many people or one person.

The pattern with 'It is...' does not change this. 'It is...' here creates a cleft sentence and can be used with both singular and plural nouns:

It is this person who I need to meet.

It is these people who I need to meet.

Peter

The LearnEnglish Team

Thanks for your reply, Peter. I enjoyed reading all the examples on cleft sentences in the link. Could you help clarify one more thing, please? Back to this example with the verb 'be'. It is you who are wrong. It is you who is wrong. Which is correct? Do we say 'It is you who are wrong.' because the pronoun 'you' takes a plural verb ==> are Or would it be better to say 'It is you who is wrong." because 'you' is a singular subject? In this example (https://www.teachingenglish.org.uk/article/cleft-sentence): 'You stole the money' can be rewritten as ‘It was you who stole the money'. So, would it mean that 'You are wrong' should be rewritten as 'It is you who are wrong'?

Hello again zhouyoumin,

I have heard both forms used in modern English. My own preference is for 'is', which keeps 'who' as a third-person form. For example, all of these sound perfectly fine to me:

It is Paul who is in charge here.

It is you who is in charge here.

It is I who is in charge here.

However, a sentence like this one sounds very unnatural to me:

It is I who am in charge here.

The example 'It was you who stole the money' does not help in any way because 'stole' is a past form, and so has no marker for person. However, you could say 'It is you who steals the money'.
