köken: From Proto-Iranian *čiš-čid / *čiš-čit, from Proto-Iranian *čiš + a suffix *čit of unknown, possibly reduplicative, origin. The former component is from Proto-Indo-Iranian *kíš, from Proto-Indo-European *kʷís, *kʷos (“who, which, what”).
köken: From *neme / *nämä "what", from Proto-Turkic *nē- (“what”). -me is an interrogative formant. Doublet of нәмә (nəmə). Cognate with Old Uyghur [script needed] (nemä, “something”); Kyrgyz неме (neme, “something”), Kyrgyz эмне (emne, “what?”), Turkmen näme (“what?”), Uzbek nima, Uyghur نېمە (nëme), نىمە (nime, “what?”), Khakas ниме (nime, “what?”), Shor небе (“thing”), etc.

köken: Probably via metathesis from ajaa (“to drive, pursue”) + -e (*ajeh), "that which spurs or drives on" > "reason". May also be inspired by aie. Another theory proposes a borrowing from an earlier (Pre-Germanic) form of Proto-Germanic *aiz (“copper, bronze”) (like *ajes- → *aješ > *ajeh), but the semantics and distribution make this questionable.
