We tend to think that we use some in positive sentences and any in negative sentences and in questions, right? Well, that’s not strictly correct. This “rule” is only the most common use of “some” and “any”.
Look at these sentences, which are correct?
I like some newspapers
I don’t like some newspapers
I like any newspapers
I don’t like any newspapers
That’s right, all of them! So what do “some” and “any” really mean? Well the difference is meaning, not grammar.
Let’s take our sentences about the newspapers. Let’s imagine that this chart represents all of the newspapers in the world.
The newspapers I like are in blue
So, we can see that some divides something into parts, but any is about all or none.
