Etymology 2

From Old Japanese.[1][2][3]

Many monolingual Japanese dictionaries[1][2][3] derive this as a contraction of Old Japanese 往ぬ (inu, to go away; to pass (such as time); to pass away, to die); however, the meaning does not seem to make sense in the context of the verb ending -nu.

More recent work by Bjarke Frellesvig and others suggests that -nu may have originated from an ancient copular or stative verb.


(romaji -nu)

  1. marks the end of action:
    1. (after the 未然形 (mizenkei, incomplete form) of a verb) the negative: indicates negation of the action, ending without starting or occurring -- not
       (かぜ) ()
      kaze ga tatanu
      the wind does not rise / does not pick up
    2. (after the 連用形 (ren'yōkei, continuative or stem form) of verb) the perfective: indicates completion of the action, ending after starting or occurring -- has done, has happened
       (かぜ) ()
      kaze ga tachinu
      the wind has risen / has picked up

Usage notes

In Old Japanese and continuing in classical and later Japanese, the ending -nu and the ending -ta have both been used to mark the completion of an action, with two key differences:

  1. -ta was not used after the 未然形 (mizenkei, incomplete form) of a verb, and thus was not used in negation contexts;
  2. -nu was used mainly for verbs that indicated intransitive, naturally occurring, or unintentional actions, while -ta was used mainly for verbs that indicated transitive or intentional actions.

In modern Japanese, -nu is rarely encountered, and it often imparts a formal or archaic sense.
