Comments:VEWT 471, EDT 491. Turk. > NPers., Kurd., Osset. tel etc. Bailey 129 cites Saka ttīla 'thread, wire' and considers it the source of Turkic forms, tracing it back to *tarɵrya - cf. Pers. tār < *tarɵra. However there are no direct Iranian parallels for the Saka form (cf. Аб. 3, 288, maintaining that the Osset. and Kurd. form do not go back to Proto-Iranian but are borrowed from neighbouring languages); so the word may well be a Turkism in Saka and other Iranian languages. The Turkic origin is also corroborated by the Chuv. parallel.
