Proto-Yenisseian: *ʔulVk (~-r1-,-ĺ-)
Meaning: bladder, bubble
Kottish: ūluk
Arin: óĺau (М., Сл., Кл.)
Pumpokol: leo-xóxar (Сл.)
Comments: ССЕ 200. Werner 2, 332 says that one should rather think of a compound with *xur1 'water' (*uʎ in Werner's notation) - which is absolutely precluded by the Arin form - cf. oĺau 'bladder' vs. kul 'water'.
