Indefinite pronouns are: anyone, anything, anybody, anywhere, someone, something, somebody, somewhere, no one, nothing, nobody, nowhere.
Indefinite pronouns do not refer to any specific person, thing, place or amount. We normally use –one, -body, -thing, -where to refer to people, things or places in a general way:
Anyone could steal your purse.
Someone is knocking at the door.
There is no one to help us.
I am looking for somewhere I can park my car.
Indefinite pronouns ending in –body and –one mean the same thing, though –one is used in a more formal context.
I’m sure somebody (or someone) will tell us her phone number.
I don’t see anyone (or anybody) coming.
Note: all indefinite pronouns are written as one word except no one.
We use else after indefinite pronouns to refer to people or things in addition to the ones we already mentioned.
