* Pronoun: This is the most common usage. It stands in for a noun, referring to something unspecified.
* Adjective: It can modify a noun, meaning "any" or "every."
* Determiner: In some contexts, it acts as a determiner, specifying a quantity, like "any" or "all."
Here are some examples:
* Pronoun: "Did you find anything interesting in the attic?"
* Adjective: "I'm happy with anything you choose."
* Determiner: "I'm not going to eat anything today."
It's important to look at the context of the sentence to determine the specific part of speech.
