Grammar Explanation : Relative Clauses

Relative clauses are subordinate clauses that refer to the noun of the main clause, identifying it or adding extra information. There are two types of relative clause: defining clauses (identifying the noun or classifying it as part of a group) and non-defining clauses (adding information about the noun). This unit examines both types of relative clause and the pronouns and adverbs used to introduce relative clauses.

Relative Clauses

Form and Use

Relative clauses are subordinate clauses introduced by relative pronouns, such as that, which or who. These clauses give information about someone or something in the main clause. Compare these examples:

• I used to live in one of those houses. They have now been demolished.
• I used to live in one of those houses that have now been demolished.

Main Clause Relative Clause

The relative pronoun is the subject or object of the relative clause. It is, therefore, unnecessary to repeat the noun from the main clause or introduce a personal pronoun to replace it:

 X I used to live in one of those houses that they have now been demolished.

We usually put the relative clause as close as possible to the noun it refers to, otherwise the meaning may not be clear:

 X Jack has prepared his favourite dish from Jamie Smith’s recipe book, which he is about to eat

 ✓ Jack has prepared his favourite dish, which he is about to eat, from Jamie Smith’s recipe book.

We often avoid relative clauses in casual speech and writing, preferring shorter ways of defining or adding information:

• People who come from Wales are often quite musical. (relative clause)
• Welsh people are often quite musical. (adjective)
• People from Wales are often quite musical. (prepositional phrase)

Subjects and Objects

A relative pronoun can be the subject of a relative clause:

• Last week I saw that film which won all the Oscars.

Subject relative pronoun

Here, the pronoun is the subject of the relative clause (the film won the Oscars), even though it is the object of the main clause (I saw the film).

A relative pronoun can also be the object of a relative clause:

• Last week I saw the film which you made at college.

Object relative pronoun

Here, the pronoun is the object of the subordinate clause (you made the film).

• In defining relative clauses, we can omit the relative pronoun when it is the object of the relative clause, but not when it is the subject:

 X Last week I saw the film won all the Oscars.

 ✓ Last week I saw the film you made at college.

Defining Relative Clauses

A defining relative clause identifies or classifies a noun or pronoun in the main clause:

Identifying relative clause:

• Is this the book that you were looking for?

Classifying relative clause:

• Would all those who have booked dinner please go to the restaurant now?

(In the second example, the relative clause classifies the members of a group.)

In defining relatives, the relative clause gives information which is necessary for the sense of the sentence. In the first example above, if we say just Is this the book?, this does not convey the key meaning of the whole sentence, i.e. the book that you were looking for.

We often use defining relative clauses to describe an important quality of someone or something:

• Van Gogh was an artist who used a lot of bold, vibrant colors.

We often use a relative clause with the same pattern for emphasis, with introductory It:

• It is always violent crime that provokes the most extreme reaction from the public.

Non-defining Relative Clauses

We usually use non-defining relative clauses to add extra information about the subject of a main clause:

• ITV’s News at Ten, which occupied the mid-evening slot for many years, was a very popular program.

(main clause = ITV’s News at Ten was a very popular program.)

We can also use non-defining relative clauses to show consecutive actions:

• Heskey passed the ball to Owen, who scored a magnificent goal.

We use non-defining relative clauses mainly in writing and formal speech.

Punctuation and Pausing

We usually use commas to separate the relative clause from the main clause in non-defining relatives, but we do not use them in defining relatives:

• The tribespeople, who traded with the settlers, retained their land. (All of the tribespeople retained their land, and, incidentally, they traded with the settlers.)
• The tribespeople who traded with the settlers retained their land. (Only some of the tribespeople retained their land – this defines a group.)

The use of commas reflects the way we say the two types of relative clause.

In defining relative clauses, there is no pause between the main clause and the relative clause:

• We asked for the double room which had a sea view.

In non-defining relatives, there is a short pause after the main clause or between the two parts of the main clause:

• We were given a lovely double room ( ), which had a sea view.
• I first met Harry Gardiner ( ). who eventually became my father-in-law ( ), at a Law Society meeting.

Prepositions with Relative Clauses

We can use prepositions with relative pronouns. Where we put the preposition depends on formality:

• Informal: Have you seen the little case that/ which I keep my contact lenses in?
• Formal: This system provides a case in which the contact lenses can be kept.

Note: We do not put a preposition before the relative pronoun that:

 X This system provides a case in that the contact lenses can be kept.

Note: If we put a preposition before who, the pronoun always becomes whom. Compare:

• The people who this report is addressed to will have to consider carefully the consequences of the proposed cuts.
• The people to whom this report is addressed will have to consider carefully the consequences of the proposed cuts.

We can often use were (for places) or when (for times) instead of which + preposition:

• This is the house where I grew up/ which I grew up in/ in which I grew up.

Reduced Relative Clauses

We often ‘reduce’ a relative clause, i.e. we shorten it by omitting the pronoun and verb. We can do this with a participle phrase:

• Marilyn was the woman living in the flat underneath us at the time (= … who lived/was living in …)
• The clauses struck out of the agreement were all unimportant. (= … which were struck out/which we struck out …)

Another possibility is to use an infinitive phrase:

• Newton was the first person to really understand the laws of gravity. (= … who really understood …)

Relative Pronouns and Adverbs

General Use

This table lists relative pronouns and adverbs and how they can be used:

Notes on the table:

We sometimes use who to refer to animals, particularly domestic pets:

• Is Sheba the dog who was run over and nearly killed last year?

Whom is formal and we rarely use it in speech. We now mainly use it after prepositions:

• I am referring to the person with whom you were seen on that evening.

Note that we always use which (not who) to refer to inanimate objects.

We can also use which to refer to the ‘idea’ of a whole clause:

• When he came home, he was unusually attentive, which made her very suspicious.

Here, which refers to the fact that ‘he was unusually attentive’.

We can use that to refer to people or objects, but we usually prefer to use who for a person when the pronoun is the subject of the relative clause:

• Ms Harrison is the lawyer who/that has been chosen to represent you.

Note: We do not use that in non-defining relative clauses:

 X This offer, that will not be repeated, must end next week.

Note: In US English that is more common than which or who in defining relative clauses.

It is possible, though not very common, to use whose to refer to objects.

• It would only be possible to colonize planets whose atmosphere contained enough oxygen to sustain human life. (= the atmosphere of which)

We often omit a relative pronoun when it refers to the object of a defining relative clause:

• The girl (who) I met in the florist’s was at the party. (= I met the girl.)

We cannot omit the pronoun if it is the subject of the clause:

 X The girl works for the florist in the High Street was at the party.

 ✓ The girl who works for the florist in the High Street was at the party.

Note: We cannot omit an object relative pronoun in non-defining relative clauses:

 X Last year’s winner presented the cup, each holder keeps for the year.

 ✓ Last year’s winner presented the cup, which each holder keeps for the year.

We can use which or that + a preposition instead of where:

• Mozart’s birthplace and the house where he composed ‘The Magic Flute’ are both now museums.
• Mozart’s birthplace and the house that he composed The Magic Flute’ in are both now museums.

We can use that as an alternative to when in defining relative clauses:

• I remember – it was the day when/ that the heatwave started.

We can use which or that + a preposition instead of when:

• The attacks continued up to the day on which the agreement was signed.

The only noun which takes why as a relative pronoun is reason:

• Sometimes he thought her clear morality was the reason why/ that he loved her.

We can use which + for instead of why.

• High taxation is often the main reason for which governments fall.

Note: It is possible to use relative adverbs without the noun to which they refer:

• It’s (the place) where that rock festival is held every year.

We use what to mean ‘the thing that/ which’. The clause containing ‘what’ is a nominal clause, i.e. the whole clause acts as a noun, either a subject or an object. While ‘what’ isn’t used in the same way as ‘that’ or ‘which’ it can fulfill the same functions as the other relative pronouns:

• Why don’t you tell the police what you told me yesterday?

In this example what you told me yesterday is the object of the verb tell. It means the same as:

• Why don’t you tell the police the story (that) you told me yesterday.

We cannot use what to replace who, which or that:

 X It was the money what I wanted, not the fame.

 ✓ It was the money (that) I wanted, not the fame.

This could be expressed as:

• The money was what I wanted, not the fame. (= the thing that I wanted)

Modifying a Relative Pronoun/ Adverb

We often use modifiers, such as all of and many of before which or whom in a non- defining relative clause to refer to the subject or object of the clause:

• The supermarket removed from the shelves all of its jars of tomato puree, several of which were found to contain fragments of glass.
• The college entered over a hundred students for the exam, all of whom passed.
• We interviewed fourteen applicants for the post, none of whom we thought suitable.

Whichever, Whenever, etc.

In defining relative clauses we can modify the pronoun or adverb with -ever to give the meaning of anything, anyone, anywhere, etc.:

• Use whichever phone you want – they all have outside lines.
• I’d like to meet whoever did that to the garden hedge!
• You can put the photo wherever you think it looks best. I don’t mind.

Controversial School to Close

Brockenhurst School, which opened as an educational experiment in 1974. is to close this summer. All the teachers (0) who are currently employed by the school will be relocated to other schools in the area (1) which have staff vacancies.

Brockenhurst was founded by (2) Sir Patrick McDonald, who comes from Inverness, at a time when new educational theories were welcomed by the establishment and experiments in education were supported. However, in recent years, such initiatives have been frowned upon as successive governments have urged a ‘back-to-basics’ approach.

The school currently employs 28 teachers, (3) all of whom come from the holistic school of education. Most of the teachers have been at the school for at least 15 years. There are approximately 780 students (4) who are of different ages at the school, and they will all transfer to schools in the region. Staff (5) who are currently living at the school will be found alternative housing by the local council.

Sir Patrick was the first person (6) who was informed of the government’s decision and he passed the bad news on to staff and students at a meeting (7) which was held last week. Sir Patrick, who is 62, has decided to take early retirement. Although Sir Patrick himself was unavailable for comment, a spokesperson for the school told us. ‘We are all very sorry about the closure. For over 25 years we have run an establishment (8) which has been dedicated to making learning a rich and enjoyable experience. All the staff and students (9) who have been participating over the years will agree that this is a sad day not only for the local community but for education in this country as a whole.’

Example:

(0) who are currently employed by the school => currently employed by the school

• Tourism today is an industry V has grown so much in recent years that in many – which
• countries it provides the greatest single contribution to the country’s revenue ✓

1. But is it always a good thing? Mass tourism which is a relatively recent
2. phenomenon brings with it a whole raft of problems. First, it means that a
3. country’s economy may rely on an industry which is wholly seasonal, with
4. the consequence that the huge numbers of people work in tourism during the
5. season have no income during the rest of the year. Some find wherever work
6. they can, but others may turn to a government that is already receiving lower
7. revenues for support.
8. Second, it is true that in many countries tourists are destroying the very
9. sights they flock to see them. They take home pieces of an ancient monument
10. or of a coral reef which will gradually result in erosion of the attractions and
11. therefore of the industry. While this kind of destruction may be wholly
12. unintentional, a certain type of tourist what wants only a ‘good time’ can be
13. very destructive in a different way: they drink too much, pick fights and
14. destroy the clubs and bars where they are drinking in. Obviously, it is then
15. this behavior by that the local community judges all members of that
16. nationality group, creating enmity between races rather than fostering
17. empathy, which should be one of the main advantages of tourism.
18. Finally, there are many places tourism is threatening a well-established
19. way of life: people whose livelihoods traditionally come from older
20. industries, such as agriculture or fishing, are finding new jobs and wealth in
21. the over-developed tourist regions, but at what cost? It is sometimes difficult
22. to understand exactly which a country gains from tourism.
