A, some, any: countable and uncountable nouns

Use a/an, some, and any differently depending on whether a noun is singular countable, plural countable, or uncountable.

Overview

What this grammar does

Use a/an, some, and any differently depending on whether a noun is singular countable, plural countable, or uncountable.

Form and rules

How it works

1

Use a/an with one singular countable noun: a chair, an apple.

2

Use some with plural countable nouns and uncountable nouns in many positive sentences: some books, some rice.

3

Use any with plural countable nouns and uncountable nouns in many questions and negatives.

4

Some is common in offers and requests when we expect or hope for a positive answer: Would you like some tea? Can I have some water?

5

Uncountable nouns such as water, money, information, and furniture do not normally have a plural form or use a/an.

A closer look

Meaning and use

Countable nouns can be singular or plural; uncountable nouns are not normally counted individually. This affects which determiners can be used.

Some is common in affirmative sentences, while any is common in negatives and questions. A/an is only possible with one singular countable noun.

Examples

See the pattern in complete sentences

a sandwich

some sandwiches

some coffee

We don't have any milk.

Would you like some cake?

Common mistakes

What to avoid

a water
some water

Water is normally uncountable, so a/an is not used directly with it.

I don't have some questions.
I don't have any questions.

Any is the usual choice in negatives.

The test combines multiple choice, gap completion, error correction, and sentence building so students have to recognise and produce the grammar, not simply reread the rule.
