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.
