S.v. νύξ, νυκτός 'night' < PIE *nekʷt-, nokʷt- 'night' (perh. from *negʷʰ- 'become dark' with a *-t- root extension).
S.v. Alb. nát/ë, -a 'Nacht, Morgendämmerung, früher Morgen', from the inherited IE word for 'night' (cf. Ved. nák, Lith. naktìs, Lat. nox, noctis, etc.).
S.v. Lith. naktìs 'night', from PIE *nokʷ-t- (cf. Skt. nákt-, Hitt. nekuz [gen.sg.] 'in the evening', Gk. νύξ, Lat. nox, Goth. nahts).
S.v. Proto-Slavic *noktь 'night', from PIE *nokʷ-t- (cf. Skt. nákt-, Hitt. nekuz [gen.sg.] 'in the evening', Gk. νύξ, Lat. nox, Goth. nahts).
S.v. Bret. nos 'nuit, soir', from Old Breton nos 'nuit', corresponding to Co. nôs (OCo. nos), W nos, and OIr. nocht, all going back to Celtic *nok-ti-, apparently from Lat. nox.
S.v. Old Welsh nos 'night' (MW nos, OC nos, OB nos; cf. OIr. innocht < PIE *nokʷt-stu-, IE *nekʷ-(t-), *nokʷ-(t-).
S.v. OLith. naktìs 'Nacht' (BSl. Latv. nakts 'Nacht', OPr. naktin 'Nacht', OCS noštь), from PIE *negʷ- 'dunkel werden, dämmern' *nókʷ-t-, *nekʷ-t- 'Nacht' (cf. Hitt. nekuz (mēhur) 'Abend(zeit)', Ved. nákt- 'Nacht', Gk. νύξ, νυκτός 'Nacht', Alb natë 'Nacht, Morgendämmerung', Lat. nox, noctis 'Nacht', OIr. innocht 'heute Nacht', OW nos 'Nacht', Bret. noz 'id.', Goth. nahts 'Nacht', TochA nokte (adv.) 'nachts').
Cf. s.v. Hitt. neku- 'to become evening', reconstructing the original root alternatively as *negʷʰ- on the basis of Gk. ἔννυχος 'nightly' and the Hitt. velar <-ku->.
S.v. Proto-Germanic *naht- 'night', from PIE *nokʷ-t- (cf. Hitt. nekuz 'in the evening' < *nekʷ-t-s; Gk. νύξ, νυκτός 'night', Lat. nox, noctis 'id.', Lith. naktìs 'id.', OCS noštь 'id.' < *nokʷ-t-).
S.v. Proto-Celtic *noxtV- 'night', from PIE *nokʷt- 'night' (cf. Hitt. nekuz (mēhur) 'at the time of night', Skt. nákt-, Gk. νύξ, Lat. nox, Lith. naktìs, OCS noštь, Alb. natë, TochB nekcīye 'at night'). Matasović considers the Middle Welsh nos a loanword from Lat. nox., but cf. [Falileyev 2000](src-240):121 who considers it inherited.
S.v. Ved. nakt- 'Nacht' (YAv. upa.naxtar- 'an die Nacht angrenzend', Wakhi naγd 'Nacht'), from PIE *nókʷt-s (nom.sg.) ~ nékʷt-s 'Nacht', perhaps assimilated from *ne/ogʷ-t-, cf. Hitt. ne-ku-[uz]-zi 'wird Abend' < *negʷ-ti. Cf. Hitt. nekuz (gen.sg.) 'of the evening', Gk. νύξ (νύκτ-), Lat. nox (noct-), Goth. nahts, Lith. naktìs, OCS noštь, etc. 'Nacht'.
S.v. Alb. natë 'night', from Proto-Albanian *nakti- corresponding to IE *nokʷt- (cf. Skt. nakt-, Gk. νύξ, Lat. nox, etc.).
Cf. s.v. *negʷ- 'dunkel werden, dämmern' (IEW 762-3). As a verbal root only Hittite (Hitt. nekuzzi 'es wird dunkel, es dämmert' < *negʷ-/n̥gʷ-). Cf. n1 regarding the derived t-stem *nógʷt-/*négʷt- 'Abend, Nacht'.
The Brittonic forms MW, MCorn., OBr., MBr. nos 'night' etc. are based on *nox(s)s < PIE *nókʷts. Contrary to this, it is traditionally assumed that nos is based on a suffixed form PCl. *noxt-stu-, as suggested by Pedersen (1909, 123) and followed e.g. by Fleuriot (1964a, 271), Matasović (2009, 294). PIE *nokʷ-t- is also found in the adverb OW henoid, MW henoeth, MBr. henoez, MCorn. haneth 'tonight', lit. 'this night', which contains pronominal *se- or *so- as a first element and Dat/Loc.Sg. PCl. *noxt-i or AccSg. *noxt-am as a second (Schrijver 1997, 24).
S.v. Wa. naɣ̌d 'ночь', from Old Iranian *naγda- < *naxta(r)- (cf. Av. [upa.]naxtar-, Ved. nákt-, Lat. noct-is).
S.v. PS *noktĭ.
S.v. 1. *negʷ- 'dunkel werden, dämmern' (LIV 449, IEW 762f.). PIE nom.sg. *nokʷt-, gen.sg. *nekʷt- 'night' from the root *negʷ- 'to become dark' (LIV 449) with devoicing of the final consonant next to *-t-. See fn. 1 with a discussion of the different stem analyses and inflectional patterns which have been suggested for PIE.
S.v. Lat. nox 'night', from PIE *nógʷʰ-t-s (nom.sg.), négʷʰ-t-s (gen.sg.) 'night', following the root reconstruction of Kloekhorst (2008:602).
