|Some||In positive statements.||I gave him some money.|
We bought some food.
|Any||In negative statements.||She didn't have any money.|

Some is used in positive statements.
It is also used in questions where we are sure about the answer.
“Did he give you some tea?” (= I'm sure he did.)
“Is there some fruit juice in the fridge?” (= I think there is)
Some is used where the question is not a request for information, but a way of making a request, encouraging or giving an invitation.
“Could I have some books, please?”
“Why don't you take some books home with you?”
“Would you like some books?”
Any is used in questions and with not in negative statements.
“Have you got any tea?”
“He didn't give me any tea.”
“I don't think we've got any tea left.”
Something, Anything, Someone, Anyone etc.
Compound nouns with some- and any- are used in the same way as some and any.
“Someone is sleeping in my bed.”
“He saw something in the garden.”
“I left my glasses somewhere in the house.”
“Are you looking for someone?” (= I'm sure you are)
“Have you lost something?” (= I'm sure you have)
“Is there anything to eat?” (a real question)
“Did you go anywhere last night?”
“She didn't go anywhere last night.”
“He doesn't know anybody here.”
There is a difference in emphasis between nothing, nobody etc. and not ... anything, not ... anybody:
“I don't know anything about it.” (= neutral, no emphasis)
“I know nothing about it.” (= more emphatic, maybe defensive)
“ Is there anybody who speaks English here?”
“There is nobody in the house at the moment.”
“Does anybody have the time?”
“When I arrived there was nobody to meet me.”
ANY can also be used in positive statements to mean 'no matter which', 'no matter who', 'no matter what':
“You can borrow any of my books.”
“They can choose anything from the menu.”
“You may invite anybody to dinner, I don't mind who comes.”
