  • 10th-century Byzantine: /ˈne.fos/[1]

Forms

νέφος (néphos) n (genitive νέφεος or νέφους); third declension[1]

Etymology

It is inherited from Proto-Hellenic *népʰos,[1] inherited from Proto-Indo-European *nébʰos (“cloud”), a neuter /s/-stem of the root *nebʰ-.[1][2][3] Cognate with Sanskrit नभस् (nábhas, “cloud, mist, sky”), Hittite nepiš (“sky”) and Proto-Slavic *nebo (“heaven, sky”).[2][1] The Greek νεφέλη (nephélē), with an /l/-suffix, matches Latin nebula (“mist, cloud”).[2][1] Beekes considers ὄμβρος (ómbros, “rain”) unrelated, though Babiniotis thinks it may belong here.[2][4] LIV takes impersonal verbs such as συννεφέω (sunnephéō) “it is cloudy” to be old.[2]

Ancient writers explained it in other ways: Chrysippus derived it from a negation and φάος (pháos, “light”), since a cloud lacks light, and Philoxenus from νείφω (neíphō, “to snow”).[5]

Earliest recorded meaning

In Homer it is a cloud or mass of clouds, and also, figuratively, the dark cloud of death.[6][7]

Semantic evolution

Homer already uses it for a dense crowd, a cloud of warriors or of birds, and for the storm-cloud of war.[7] Poets use it for clouds of death, forgetfulness, blindness and grief,[6][7] and Euripides speaks of a cloud of lament and of a cloud upon the brow.[6][7] Prose has it of real clouds, as when Plato names cloud and mist together, and Demosthenes of a danger that passed like a cloud.[6]

Medieval Greek kept it.[8] In Modern Greek νέφος (néfos) is a learned word for a cloud, also for the cloud of pollution over a city,[9] and Triantafyllidis takes this sense as a semantic loan from English cloud, and Babiniotis from English smog.[9][4]
