nubile
Origin
From French nubile, from Latin nūbilis (“marriageable”), from nūbō (“marry, to take as husband”), from Proto-Indo-European *snewbʰ- (“to marry, to wed”). Possibly cognate with Ancient Greek νύμφη (númphē, “bride, young wife, nymph”) (English nymph), but this is disputed.
nudnik
Origin
From Yiddish נודניק (nudnik), from the root of נודיען (nudyen, “to bore”) + ־ניק (-nik, noun-forming suffix) (English -nik), both of Slavic origin. The root derives from Proto-Slavic *nùditi (“to compel”) and the noun *nùďa (“need, necessity”), ultimately from Proto-Indo-European *new- or *neh₂w- (“to lack, need; to perish”). The suffix is from Proto-Slavic *-ьnikъ (forming agent nouns and objects). Compare Russian ну́дный (núdnyj, “tedious”), Ukrainian нудни́й (nudnýj, “boring”), Polish nudny (“boring”), Slovak nudný (“boring”), Old Church Slavonic ноудити (nuditi) or нѫдити (nǫditi, “to compel”), Hebrew נוּדְנִיק (“nag”). See also English need, and compare needy for the semantics.
nuel
Origin
From Middle English newel, niwel (“right down”, adverb), from Old English nēol, nȳwol, nēowol, neowol, niwol, nihol (“precipitous, headlong, prone, prostrate, obscure, deep down, low, profound, abysmal”), of uncertain origin. Possibly a variant of nifol (“dark, gloomy, obscure”), from Proto-West Germanic *nebul, from Proto-Germanic *nibulaz, *nebulaz (“mist, fog”), from Proto-Indo-European *nébʰelos, from *nébʰos (“cloud, mist, moisture”); or more likely, from Proto-Germanic *nīhwulaz (“descending; low”), from Proto-Indo-European *kneygʷʰ- (“to tend; incline; lean toward; bend”), from *ken- (“to press; pinch; kink”). If derived from *nibulaz, then cognate with Dutch nevel (“mist, fog, haze”), German Nebel (“fog, mist, haze, nebula”), Icelandic nifl (“fog, darkness”), Icelandic njól (“mist, night, darkness”), Latin nebula (“fog, cloud, vapour”), Ancient Greek νέφος (néphos, “cloud”). If derived from *nīhwulaz, then cognate Old Frisian niwul, Middle Low German nīgel, nugel, nule, nūl (“forwards; forward over”), Middle Dutch niel (“thrown forward on the ground; prostrate”) (Dutch nuul-, vernielen).
