Answer:
Indefinite pronoun

An indefinite pronoun is a word that replaces one or more nouns (a noun can be a person, animal, thing, idea, place, etc) in a general way, in other words, without being specific to what noun is referring to. Pronouns such as many, several, another, anything, any, anybody, anyone, either, neither, nobody, all, none, someone, some, each, everybody and few are all examples of indefinite pronouns.
