Proto-Yenisseian: *wVs
Meaning: blue
Kottish: urek-bas (Ass.) (Кл.) 'blue'
Arin: bis (М., Кл.) "голубой", (Сл.) "синий"
Comments: ССЕ 294. For the first part of the Assan compound cf. Kott. oreäk, ureäk 'green'. Werner (1, 131) suggests that the Ass. form means "like green", which is quite dubious if we take into consideration the independent Arin form bis. Note also Kott. bosarak 'fox-colored' - which may be actually a compound similar to urek-bas, but with a different order of components.
