Somebody, Anything, Nowhere ...

Combine some-, any-, no- and every- with -body/-one (people), -thing (things) and -where (places). The endings -body and -one mean the same: somebody = someone.

• some- in positive sentences: There's somebody at the door.
• any- after not and in questions: I didn't see anything. It also means "it doesn't matter which": Sit anywhere.
• no- already contains the negative, so the verb stays positive: There's nothing to eat = There isn't anything to eat. Never use no- together with not.
• every- means all: Everybody passed. I looked everywhere.

These words take a singular verb: Everyone is here. No one is two words (British English also writes no-one).
