Thank you very much!

Give us a sentence and we can tell you which it is in context. Examples:

Would you like some pie? — adjective
I’ve already had some, thanks. — pronoun
Now I’m going to have to let my belt out some. — adverb

@Jeruba There must be some way you can finish that pie.

@erichw1504, won’t you have some with me?

@Jeruba By golly, I would love to have some with you!

Some pie, @erichw1504, some pie.

Tch.

@Jeruba Oooooh, I apologize. I took your some the wrong way.

Altho dictionaries list it as an adjective, it’s really a determiner – the same as the/a/this/that. It fills the same slot as these words.
Would you like the pie?
Would you like some pie?
but not:
*Would you like the some pie?
If it was really an adjective, that last sentence would be grammatical.

Excellent distinction, @morphail. Thank you. I suppose “any” and “no” would fall into the same category, in at least one of their senses.

Yes. here’s a list
