Some / Any
Level A1 · Articles & Determiners
Use some in affirmative sentences, and in questions that are offers or requests, where you expect the answer to be yes: I have some books; would you like some tea? (an offer). Use any in negative sentences and most other questions, where you don't know or expect the answer: I don't have any books; do you have any siblings?
Both some and any combine with plural countable nouns (some books, any apples) and uncountable nouns (some water, any information), not with singular countable nouns in this quantity sense — not some book, not any apple. There is one exception, covered below: any meaning 'it doesn't matter which' does attach to a singular noun — take any book you like.
A few special cases worth knowing:
- some in a question = an offer or a polite request, expecting yes: would you like some help? could I have some water?
- any in an affirmative sentence = 'it doesn't matter which': you can take any book you like; call me at any time.
- some/any + one/thing/body/where combine the same way: someone, anything, nobody, anywhere.
The most common mistake is using any in an offer or polite request, or some in an ordinary question: would you like any tea? sounds odd — an offer expects yes, so it needs some; do you have some time? in a neutral, open question should be do you have any time?, since you don't yet know the answer.
Quick check: affirmative statement or a friendly offer/request → some. Negative statement or a genuine, open question → any. 'It doesn't matter which one' → any, even in an affirmative sentence.
