Indefinite Pronouns

We use indefinite pronouns to refer to people or things without saying exactly who or what they are. We use pronouns ending in -body or -one for people, and pronouns ending in
-thing for things.

We use ANYONE (ANYBODY) only with negative sentences or questions. For affirmative sentences we use SOMEONE (SOMEBODY) and for affirmative sentences with a negative meaning we use NO ONE (NOBODY)

AFFIRMATIVE: SOMEONE told me that you have a new car.
NEGATIVE: NO ONE told me that you have a new car.
INTERROGATIVE: Did ANYONE tell me that you have a new car?
