Forms
νῠ́ξ (núx) f (genitive νῠκτός); third declension[1]
Etymology
It is inherited from Proto-Hellenic *núks,[1] inherited from Proto-Indo-European *nókʷts (“night”), the old word for “night”, kept in most Indo-European languages.[1][2] The ⟨υ⟩ in place of ⟨ο⟩ is explained by Cowgill's Law.[2] Schindler reconstructed a root noun with nominative *nókʷt-s and genitive *nékʷt-s.[2]
Forms with an aspirate and without ⟨τ⟩, such as νύχα (núkha, “by night”) (Hesychius), ἔννυχος (énnukhos) and νύχιος (núkhios), are found only in Greek and in Anatolian, beside Hittite neku-zi (“to become dark”); following Kloekhorst, Beekes takes both to point to a root *negʷʰ-, lost in Indo-European after Anatolian split off, so that *negʷʰt- was later assimilated to *nekʷt-.[2][3]
Cognate with Latin nox, Sanskrit नक्त् (nákt), Lithuanian naktìs, Old Church Slavonic нощь (noštĭ), Albanian natë and Old English niht (whence English night).[1][2]
An ancient grammarian, Philoxenus, quoted in the Etymologicum Magnum, derived it from νύσσω (nússō, “to prick”), as the time that pricks people into sleep.[4]
Earliest recorded meaning
In Homer it is night, as opposed to day, with epithets such as “ambrosial” and “deadly” (Iliad 24.363, 16.567);[5][6] the genitive νυκτός (nuktós) serves as an adverb, “by night” (Odyssey 13.278).[5]
Semantic evolution
Homer also uses it for a darkness that a god sends to protect a man, and for the night of death; the tragedians use it as a figure for what is dire.[6] Hesiod and later poets make Night a goddess, the mother of Day, Sun and Sleep, and Hesiod also uses the word for the darkness of the west, where the sun sets.[6] Among its derivatives is νυκτερίς (nukterís), the bat, found from the Odyssey and Herodotus on.[7] In the New Testament it is the time between sunset and sunrise, and the period of the night watches.[8]
Medieval Greek turned the accusative νύκτα (núkta) into Byzantine Greek νύχτα (núkhta), changing the ⟨κτ⟩ cluster to ⟨χτ⟩;[9] the modern word is Modern Greek νύχτα (nýchta).[9]
