Some is used in positive statements; any is used in negative statements and
questions:
▶️ Positive: I want some bread
▶️ Negative: I don’t want any bread.
▶️ Question: Do we have any bread in the house?
There is an exception – some is used in questions if you are offering something to
someone, or asking for something:
▶️ Offering something: Would you like some bread?
▶️ Asking for something: Can I have some extra ketchup for my fries, please?
Only use some and any with uncountable nouns and plural countable nouns:
▶️ She wants some water.
(water = uncountable noun)
▶️ He hasn’t received any e-mails yet.
(e-mails = plural countable noun)
Don’t use some or any with singular countable nouns:
▶️ Can I have some apple? (apple = singular countable noun)
Can I have an apple?
▶️ Paul doesn’t have any car. (car = singular countable noun)
Paul doesn’t have a car.
