아무+(이)나/아무+도 — Anyone, Anybody, No one, Nobody

The word '아무' is used to express the not choosing of any specific thing in the sense of "any" (e,g anything, anyone). Depending on the particle that follows it, it can either refer to people or things. To refer to people, the word 아무+나 is used to indicate "anyone" or "anybody", while 아무+도 is used to indicate "no one" or "nobody". Note that a negative expression must follow the use of 아무도.
