Comments: ССЕ 214. Werner 1, 167 <*t'Vg->. Werner doubts the relationship of Kott. tagai 'head' (comparing it instead with Ket dáɣai 'Kopf mit zerzaustem Haar', see Werner 1, 178) - although it displays absolutely the same correspondence as *cīk 'snake' q.v. (Kott. tēg, tēx) and *cä-xur 'thin (of fluid)' (Kott. theūr).
