One and Ones: Choosing Without Repeating

By the end: I can use one and ones instead of repeating a countable noun.

Created by , British English teacher.

I’m studying:

Try the activities, then check your answers.

Start here

Imagine choosing between two bags in a shop.

Read each explanation, say your answer aloud, then open the model and try again. You may write your answer if you prefer. Use invented personal details whenever you like.

Useful preparation: Singular/plural countable nouns, demonstratives and simple adjectives; basic comparatives are optional support.

Choose a play button when you are ready.

Learn 1

One replaces one countable thing

Use one when a singular countable noun is already clear: Which bag? The blue one. One means bag here. Keep the adjective before one. This one and that one can also identify a single object.

I like the blue one.

That one is mine.

Choose from the two bags in the recording

The red bagThe red one is large.
The blue bagThe blue one is small.

“I want the blue one.” Here, one replaces bag. The colour identifies the bag the speaker wants.

A large red bag on the left and a smaller blue bag on the right.

Ones replaces plural things

Use ones instead of a plural countable noun: Which shoes? The black ones. Match is or are to the meaning: The blue one is small. The blue ones are small.

I like the black ones.

The small ones are in this box.

With plural shoes, use ones

The shoes selectedThe black ones.

Ones replaces shoes.

The shoes not selectedNot the brown ones.

The colour distinguishes the two pairs.

Each picture shows a pair. The noun shoes is plural, so use ones.

Replace the noun and keep the size and place

Big boxesThe big boxes are on the floor.

Boxes introduces the plural noun.

Small boxesThe small ones are on the table.

Ones refers to boxes; are agrees with the plural.

The pictures illustrate the size and location contrast. The recording does not specify an exact number of boxes.

Ask which one or which ones

Ask Which one? for a single object and Which ones? for plural objects. Use one/ones only when a countable noun is clear. It does not replace uncountable milk itself; name a bottle or carton if that is the thing you mean.

Which one do you want?

Which ones are yours?
