Mnemonic

おやすみ oyasumi — お (honorific) + 休み (yasumi, rest). Literal: "rest [well]" — sleep cast as rest. Polite form おやすみなさい (nasai = polite imperative). Said before bed to family, partner, friends. The same kanji 休 appears on shop signs as お休み ("closed for the day"). A noun derived from 休む (yasumu, to rest) ossified as a greeting — one kanji branches between commerce ("closed") and intimate farewell ("goodnight").

Quick check

  1. How does 休 work for both "shop closed" (お休み) and "goodnight" (おやすみ)?
