Proto-Yenisseian: *čǝG-
Meaning: crust on snow
Ket: tъ̄-tik
Yug: tъ-tik / tъu-tik
Kottish: šāk, šāx, šāg
Comments: ССЕ 216-217. Ket and Yug reflect a compound with *tiχ "snow" (q.v.); Yug has a assimilation tъ-tik < *čǝ:-tik (old initial affricate is indicated by the Kottish form). In Kottish cf. also u-šōx, u-šou 'ice' - possibly *ul-šōx lit. 'water-crust'. Werner (2, 305, 436) apparently does not accept the assimilatory explanation for Yug t- and consequently has to separate the Kott. form (accepting for it the reconstruction *čǝG-) from the Ket and Yug one. For the latter he gives a protoform <*thǝ / *thǝ̀gǝ́> and unites it with tʌ- in *tǝʔlap 'bread crust' q.v. - which I think is hardly justified, see under *tǝʔlap. One should also mention that Kott. ušōx 'ice' is utterly strangely etymologized (Werner 2, 376) as ūša 'far' + *ku / xu 'ice'; and finally that Werner lists (without etymology, see 1, 166) Yug čɔ́χɔr 'Rauhreif' - which must be a compound *čǝG-qo-xur, with *čǝG-qo- being an exact match for Kott. šāk, and proving that Yug t- in tъtik is aq result of assimilation.
