Remember 'some' and 'any' are quantifiers. They are used for unspecified quantities. Simply, some is used for positive sentences and any is used for negative sentences. Both some and any can be used in questions.
- I have some money.
- There is some coffee in the jar.
- There are some cookies in the tin.
- There aren't any biscuits.
- There isn't any milk.
- Do you have any sugar?
- Do you have some brown bread?
