Determine the class of the italicized pronoun. any of us could be the winner. personal relative interrogative demonstrative indefinite reciprocal intensive reflexive

In the sentence "Any of us could be the winner", there is two pronouns which are any and us. The word "us" is a personal pronoun, more precisely a personal objective one. Personal pronouns are used to replace a noun within the sentence or clause. They can be either subjective when the subject of a sentence is the person or thing that fulfills the action (I, he, she, it, they, we, and you) or objective when they indicate the recipient of an action or motion and when they come after verbs and prepositions (me, her, him, it, you, them, and us).On the other hand, the word "any" in this sentence acts as an indefinite pronoun since it does not refer to any specific person, thing or amount. It is vague and "not definite". Moreover, such word can also act as a determiner when used before nouns:

"I dont have any sugar."
