Countable and Uncountable Nouns in English

If you are talking about a single item, use “a” or “an.” The usage remains consistent across positive, negative, and question sentences.

Countable Singular Nouns

Positive: I have an apple.

Negative: I don’t have an apple.

Question: Do you have an apple?

Countable Plural Nouns

For plural nouns where the exact quantity doesn’t matter, use “some” in positive sentences and “any” in negative and question sentences. Remember that “some” and “any” can be used for both countable and uncountable nouns.

Positive: I have some apples.

Negative: I don’t have any apples.

Question: Do you have any apples?

Note: “Some” can also be used for offers and suggestions.

“Some” and “any” are also used with uncountable nouns.

Negative: I don’t have any money.

Question: Do you have any money?
