Комментарии:Ozawa 120-121, АПиПЯЯ 72, 92, 274. The Jpn. form may reflect a contraction of the suffixed *či̯ū́n(u)-gV, but since loss of *-n- is not attested elsewhere, one cannot exclude a monosyllabic reconstruction *či̯ū, with a suffix *-n added in Turkic and TM. Cf. also Mong. *činar 'quality, image' (see Владимирцов 172, Poppe 15, 69; in VEWT 478 and KW 441 considered to be borrowed < Uygh. tɨnar).
