아무 -(이)나 [Intermediate Grammar]

- 아무-(이)나

→ It means 'whatever, it doesn't matter.? by combining a modifier form of an unspecified one '아무 (refer to Intermediate 2, Lesson 6) with a postposition of choice'(이)나.' It can be used by putting an additional postposition form before'(이)나' in a row. When a noun is a person, it can be used in the form of '아무나', or '아무한테나' instead of that noun.
