Comments:An expressive kinship "nursery" word with the typical structure *VCV; the root must have denoted some elder relative, both male and female. Deriving TM *asī from a Chinese (ТМС 1,55) or Sino-Korean (SKE 15) source is quite impossible. The Mongolian reflexes are problematic: Mong. eǯei 'mother, elder sister' (whence Yak. eǯīj, Dolg. eǯij, see Кал. V 27, Stachowski 43) is probably < Turkic.; Mong. ečige 'father' reflects rather PA *ĕ́t`è q. v. One should, however, note an isolated Dagur form ačā 'father' (Тод. Даг. 122), whence certainly Solon ača id. and possibly Evk. (Vit.) ači 'ancestor' (ТМС 1, 59).
