Comments:See ТМС 2, 380-382 (several different roots are united there, among which, e.g., Man. čaɣan is obviously < Mong., but other forms are genuine - despite Doerfer MT 116). Note that Manchu šaχun as well as Nan. čāGǯã, Ul. čāgǯa(n) and Orok tagda(n) may also reflect suffixed forms of *šā(ŋ)- 'white' (v. sub *šā̀ŋu).
