Комментарии:KW 232, Poppe 20, 115, Martin 240, ОСНЯ 1, 354. Mong. is hardly borrowed from Turk., despite Щербак 1997, 139. The root tends to contaminate with *gi̯óro q. v. The vowel reflex in Korean is somewhat unclear (*kark- or *kǝrk- would be expected), otherwise all evidence points to *k`irga. The relation of Manchu xergen 'line, scratch, notch' is not quite clear: the word is certainly borrowed (because of -rg-), but the source is unknown; equally unclear is the isolated Manchu qarqa- 'scratch with chopsticks, scrape on the fiyoo instrument' (compared with Kor. by Lee 1958, 113); perhaps in both cases we are dealing with loanwords Manchu < Kor.(?)
