We bought some clothes.
Do you have any milk?
Do not use some or any with a singular countable noun:
Would you like some piece of cake?
Note also that we don’t use some to talk about things in general. For this, nothing is needed before the noun:
Katie loves animals. (she loves animals in general)
Katie loves some animals.
We saw some animals running away. (we saw specific animals)
So when do we use some and when do we use any? In general, we use some in positive sentences and any in negative sentences:
There were some pictures on the wall.
There weren’t any pictures on the wall.
There weren’t some pictures on the wall.
We also use any if we want to emphasize that it doesn’t matter which one of a group of things we are talking about. This use is particularly common in sentences with if:
Please choose any colour you want.
If you have any problems, call me.
For questions, the situation is slightly more complicated. We use any if we don’t have an idea about what the answer will be or if we don’t know whether or not something exists:
Do you have any students from Russia?
Is there any butter in the fridge?
We use some if we think the answer is likely to be positive, or if we know that something exists:
Would you like some chips?
Can you lend me some money?
Finally, when you use some or any before a noun phrase beginning with a word such as the, those or our (rather than directly before a noun), you need to add of:
Some of the people were crying.
Some the people were crying.
Have you had any of this soup?
Have you had any this soup?
We also use of before a pronoun such as it, us or ours.
You need food? Here, have some of mine.
Marty made a cake but we didn’t eat any of it.
I hope these notes will help, but they seem too complicated, just remember the following:
1) Use some and any only before plural or uncountable nouns
2) Use some in positive sentences, any in negatives
3) Use any in questions (see above for more detail, but any is more common)
4) Use some of and any of if the noun has a word like the or my in front of it.
With these four basic rules, you will be correct most of the time!
