Comments:VEWT 96, TMN 2, 77, EDT 409, Федотов 2 387. Despite Fedotov čokur 'variegated' is not related, it is < Mong. čobkur (v. sub *šop`é). Despite Räsänen borrowed from Mong. can be only Yak. čakɨr 'white (of a horse)' (cf. also Dolg. čakɨr, see Stachowski 72), and perhaps the front-row forms (Kirgh. čekir, Kaz. šegir, KKalp. šegir - because of their restriction to the Kypch. area); but Mong.. čakir / čekir 'whitish' is itself an obvious Turkism (see TMN ibid., Clark 1977, 134 with doubts). The root should be distinguished from nasalized forms: Oyr. čaŋqɨr, Chuv. senker, Yak. čeŋgir, ǯeŋgir, Kirgh. čenkil, čaŋɨl with the same set of meanings ('whitish, blue', often of eyes) = Mong. (Khalkha) cenxer id.; those should be compared with Tokh. A, B tseṃ 'blue (of eyes)', Pers. zangār 'verdigris', whence Tat. zäŋgär (from Pers. zang 'rust', further derived with *zā'to leave, remain', Sak. ysāyä 'rust', Osset. zgä, see Bailey 348-349). This is most probably an Iranian loanword in Turkic, Tokh. and Mong. (although a Chinese origin - cf. MC 青 chieŋ 'blue' - is also possible). Cf. VEWT 104 (Turk. < Mong.), 531.
