Etymology

Native formation The verb is built from the kanji 直 meaning straight or direct, plus the verb suffix す, yielding a native verb with the sense of making straight, fixing, or putting right; the kun'yomi nao- forms the base for conjugation.

Origin

Old Japanese usage is well-attested in classical literature; the form became widespread in Edo-period speech and remains foundational in modern Japanese.
