We use one (singular) and ones (plural) to avoid unnecessary repetition.

See those two girls? Helen is the tall one and Jane is the short one.
Which is your car, the red one or the blue one?
My trousers are torn. I need some new ones.
See those two girls. Helen is the one on the left.
Let’s look at the photographs. The ones you took in Paris.

We often use them after Which ... in questions:

You can borrow a book. Which one do you want?
There are lots of books here. Which ones are yours?

Hello,

I wrote your example again without one and ones. Is it wrong do that?

---8<---

See those two girls? Helen is the tall [] and Jane is the short [].

Which is your car, the red [] or the blue []?

My trousers are torn. I need some new [].

See those two girls. Helen is the one on the left. [In this case I think I can't remove that]

Let’s look at the photographs. The ones you took in Paris. [In this case I think I can't remove that]

Thank You

Hello Franz,

You're right that you can't remove 'one/s' from the last two sentences. I'm afraid you can't remove it from the first two sentences, either.

All the best,

Hello,
In example 2 (Which is your car, the red one or the blue one?) can I say (Which is your car, the red or the blue?) or that is wrong?

Hello Ola Jamal,

Although you can hear some examples like this from time to time they are quite unusual and occur in very formal and/or literary use, and even there they are rare. We would generally say the sentence with 'one' rather than without.

I love it. The exercises are very helpful.

Good day everyone
This lessons are quite interesting and I am learning a lot especially through practical activities or exercises. I am suggesting from our tutor at least to give us long pieces of writings to improve our writing skills.

i just have a doubt in the below sentence.

It is regrettable that a case relating to the promotion of communal disharmony, one that had a bearing on riots and reprisals in the following months, was mired in judicial stagnation and administrative apathy for a quarter century.

in the above sentence,one that had a bearing on riots and reprisals in the following months is acting as an adjective clause for noun CASE or it is acting as a noun clause.

could you please help me.

thanks in advance

Hello ganesh4023,

The clause 'one that had a bearing on riots and reprisals in the following months' has an adjectival role. It is a particular rhetorical device which repeats the subject of the relative clause. We can rewrite the sentence with a normal relative clause in two ways:

It is regrettable that a case relating to the promotion of communal disharmony that had a bearing on riots and reprisals in the following months was mired...

or

It is regrettable that a case relating to the promotion of communal disharmony, which had a bearing on riots and reprisals in the following months, was mired...

The first sentence has a defining relative clause and the second has a non-defining relative clause; both are possible. However, there are problems with both possibilities. The first is quite a hard sentence to follow as there are two defining relative clauses in it - one reduced to a participle ('relating') and one introduced with 'that'. The second is ambiguous - the non-defining relative clause could refer to the 'a case' or to 'communal disharmony'.

Another way to phrase the sentence uses a clause which repeats the subject or uses 'one' instead:

It is regrettable that a case relating to the promotion of communal disharmony, a case that had a bearing on riots and reprisals in the following months, was mired...

or

It is regrettable that a case relating to the promotion of communal disharmony, one that had a bearing on riots and reprisals in the following months, was mired...

 

This is a clearer way to structure the sentence and also has a rhetorical effect of emphasising the point being made.

I hope that helps to clarify it for you.

 

Best wishes,
