Analysis. When used as a negative, likely from √nah or contraction of na (not) with a vowel-lengthening particle; the interrogative sense derives from the emphatic-temporal particle (common in Vedic).
Etymology. The interrogative and emphatic particle no derives from Indo-European *nu (now, then), cognate with Sanskrit nu, Greek νῦν (nyn, "now"), English "now". The negative use may conflate this with na (not). Temporal particles commonly develop interrogative force across Indo-European languages.
