Any is a determiner and a pronoun.

Any may be used as a singular or a plural pronoun, depending on whether it refers to “at least one” or “one or more.” You may use either a singular verb like is or a plural verb like are with any (although use of the plural is more common).

Pronouns are classified as personal (I, we, you, he, she, it, they), demonstrative (this, these, that, those), relative (who, which, that, as), indefinite (each, all, everyone, either, one, both, any, such, somebody), interrogative (who, which, what), reflexive (myself, herself), possessive (mine, yours, his, hers, theirs).
