A personal pronoun is a word that takes the place of a noun for a specific person or thing.
They are: I, you, we, he, she, it, me, us, him, her, they, them.
An indefinite pronoun is a word that takes the place of a noun for people, things, or amounts that are unknown or unnamed.
They are: all, another, any, anybody, anyone, anything, both, each, either, enough, everybody, everyone, everything, few, fewer, less, little, many, more, most, much, neither, nobody, no one, nothing, none, one, other, others, several, some, somebody, someone, something, such, and they (people in general).
Example:
John said that he found a set of keys that someone lost.
Personal pronouns are words that take the place of nouns for (person, place, thing); the personal pronouns are I, we, you, he, she, it, me, us, him, her, they, them. Indefinite pronouns take the place of someone or something indefinite; an indefinite pronoun does not refer to any specific person, thing or amount. Examples of indefinite pronouns are another, any, anybody, anyone, anything, each, either, everybody, everyone, everything, neither, nobody, no one, nothing, somebody, someone, something, etc.
The pronouns are: all = indefinite pronoun us = plural, objective personal pronoun anyone = indefinite pronoun you = singular, subjective, personal pronoun
There are a group of pronouns called indefinite pronouns but no group called definite pronouns. I have only seen that term used once before, it was for definite personal pronouns. The personal pronouns are I, me, you, he, him, she, her, it, we, us, they, them.
The two kinds of indefinite pronouns are indefinite pronouns that refer to people, such as "someone" or "anyone," and indefinite pronouns that refer to things, such as "something" or "anything."
