English Grammar

Difference between relative pronouns and relative clauses

What is a clause?

It is a grammatical unit consisted of a subject and predicate or verb, ranked smaller than a sentence because it is not always complete in itself.

There are different types of clauses: dependent and independent:

1/ independent = expresses a complete meaning = a sentence

2/ dependent = expresses an incomplete meaning = subordinate clause

Different combinations of clauses are possible to create a compound sentence:

1/ independent clause 1 + independent clause 2 = main clause 1 + main clause 2

“We went to the park and the ride was broken.”

“I really wanted the tomato soup, but they only had the leek soup.”

2/ main clause + subordinate clause

= independent clause + dependent clause

“I found a cat that was abandoned.”

“She is the colleague who helped me with the presentation.”

How to create a relative clause?

A main clause can be a sentence on its own: He lives in this neighbourhood,

whereas a subordinate clause needs a main clause to exist, i.e.: which is very quiet. This subordinate clause is joined to the main clause via a relative pronoun.

More examples:

He lives in the neighbourhood which is very quiet.

I enjoy sitting by the fireplace that is in the lounge.

I saw a movie star who is world famous.

What is a relative pronoun?

which, that, who, whom, why, whose, where, whoever, what, …

They are used to join 2 clauses: 1 subordinate clause and a main clause.

If we want 2 sentences to meet and merge into one we need a relative pronoun to show the link.

Depending on what the subordinate clause is giving more information on, we will use one relative pronoun or another:

who, whom, which, that, whose…

Let’s learn our relative pronouns and relative clauses:

1/ For objects:

which / that = interchangeable

We take an independent sentence: “That is the new PC”

and we add more information about that object, so we add a relative pronoun and its clause

which / that

That is the new PC which/that I told you about.

In spoken English we can remove the relative pronoun: That is the new PC I told you about.

2/ For people:

who / that (subject)

whom / that (object)

That is the neighbour who / that just moved in. (we use “WHO” when the subject of both clauses is identical)

That is the neighbour whom / that I met yesterday. (“the neighbour” is the object of the relative / subordinate clause)

In spoken English we don’t use “whom” as much as we should, instead we use “that” or “who”. But remember:

who / that (subject)

& whom / that (object)

3/ For possession:


That is the student whose grades have gone up. (The grades belong to the student)

4/ For place:


in which / at which

That is the place where I left it.

That was the building in which the fire started.

That is the bus stop at which you must wait.

5/ For time:


at which

That is the moment when I left my job.

That is the time at which I go to bed.

Why use relative pronouns and what to watch out for?

Use and common mistakes:

1/ Avoid repetition:

He has just bought a house. It is new. He really likes it. (REPETITIVE)

> He has just bought a house which is new and that he really likes. (BETTER)

2/ Differentiate object and subject:

WRONG: He is a person which I trust

CORRECT: He is a person that I trust. / He is a person whom I trust.

3/ A relative pronoun replaces a noun group. You don’t need 2 pronouns!

WRONG: This is a house that he really likes it.

CORRECT: This is a house that he really likes.

4/ Be careful with the spelling of “which”!

It is not “witch” or “whitch” or “wich”!
