Pronunciation

IPA^(key): [nɯ̟ᵝ]

Etymology 1

Derived in the Heian period from writing the man'yōgana kanji 奴 in the cursive sōsho style.

Syllable

ぬ (romaji nu)

The hiragana syllable ぬ (nu). Its equivalent in katakana is ヌ (nu). It is the twenty-third syllable in the gojūon order; its position is な行う段 (na-gyō u-dan, “row na, section u”).

Etymology 2

Originally the 連体形 (rentaikei, “attributive form”) of Classical Japanese negative particle ず (zu). In modern Japanese, the 終止形 (shūshikei, “terminal form”) (lemma, originally ず (zu)) assimilated to ぬ (nu).

Suffix

ぬ • (-nu)

(archaic) (after the 未然形 (mizenkei, “incomplete form”) of a verb) the negative indicates negation of the action, ending without starting or occurring: not
風(かぜ)が立(た)たぬ
kaze ga tatanu
the wind does not rise / does not pick up
予(よ)期(き)せぬエラーが発(はっ)生(せい)しました。
Yoki senu erā ga hassei shimashita.
An unexpected error has occurred.

Etymology 3

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.

Suffix

ぬ • (-nu)

(Classical Japanese or literary) (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
風(かぜ)が立(た)ちぬ
kaze ga tachinu
the wind has risen / has picked up
- 1943, 土井晩翠譯『オヂュッセーア』第十九歌
  多(おほ)くの女(ぢよ)性(せい)彼(かれ)を見(み)て皆(みな)驚(きやう)嘆(たん)の目(め)を張(は)りぬ。
  Ōku no josei kare o mite mina kyōtan no me o harinu.
  Many women looked at him and all opened their eyes wide with admiration.

Usage notes

In Old Japanese and continuing in classical and later Japanese, the ending ぬ (nu) and the ending つ (tsu) have both been used to mark the completion of an action. ぬ (nu) was used mainly for verbs that indicated intransitive, naturally occurring, or unintentional actions, while つ (tsu) was used mainly for verbs that indicated transitive or intentional actions. In the shift to modern Japanese, this distinction was lost, and Classical つ (tsu) developed into modern た (ta).
In classical Japanese, perfective ぬ (nu) conjugates differently from negative ぬ (nu) (ず (zu)) as shown in the following table:

	Negative ぬ (nu) (ず (zu))	Perfective ぬ (nu)
Attaches to verb stem conjugated to →	Irrealis / 未然形 (mizenkei)	Continuative / 連用形 (ren'yōkei)
Conjugates to ↓
Irrealis / 未然形 (mizenkei)	ず (zu)	な (na)
Continuative / 連用形 (ren'yōkei)	ず (zu)	に (ni)
Terminal / 終止形 (shūshikei)	ず (zu)	ぬ (nu)
Attributive / 連体形 (rentaikei)	ぬ (nu)	ぬる (nuru)
Realis / 已然形 (izenkei)	ね (ne)	ぬれ (nure)
Imperative / 命令形 (meireikei)	-	ね (ne)

In modern Japanese, ぬ (nu) is rarely encountered, and it often imparts a formal or archaic sense.
This word is morphologically an inflectional suffix. It is classified as 助動詞 (jodōshi, “auxiliary verb”) in traditional Japanese grammar.

Old Japanese

Etymology

The conjugation of this auxiliary verb appears to follow that of a defective n-row 四段活用(よだんかつよう) (yodan katsuyō) paradigm rather than a ナ行変格活用(ぎょうへんかくかつよう) (na-gyō henkaku katsuyō) paradigm, despite the fact that there was never an n-row 四段活用(よだんかつよう) (yodan katsuyō) paradigm.

Notably, this verb has no attested 終止形(しゅうしけい) (shūshikei); uses and conjugations off of にす (nisu) are seen instead. This verb also has no attested 命令形(めいれいけい) (meireikei).
