Indefinite adjective meaning: Indefinite adjectives function as adjectives. That is, indefinite adjectives modify nouns and pronouns.
Indefinite adjectives are called such because they modify nouns a non-specific or vague manner.
Most adjectives give a “definite” modification for nouns. Indefinite adjectives do not.

- This example uses an adjective, “your,” to explain to which cat the speaker is referring. There is no question as to what cat you are referring.
- some cat
- This example uses an indefinite adjective, “some,” to refer to the cat. The speaker is not referring to a specific cat.
- his car
- This example uses a possessive pronoun, “his,” to explain to which car the speaker is referring. Again, it is clear and unambiguous what car.
- any car
- This example uses an indefinite adjective, “any” to refer to the car. In other words, no specific car is mentioned at all.

“Any” is a common indefinite adjective.

The first sentence uses any to replace an item (money, perhaps) and is used as a pronoun.
The second sentence uses any as an adjective to modify money, answering the question, “How much?”
