Comments:EAS 111, KW 380, SKE 250, Poppe 13. Despite Щербак 1997, 154 we cannot assume borrowing in Mong. from Turkic. Turkic has a secondary voiced d- (one of the cases of voicing in front of -ŕ-); but a contamination of two roots is also not excluded: cf. also Mong. dar-gar, dars-gar (L 233: darsa-ɣar) 'rough, warped (of skin)'. Cf. also notes to *t`ĕ́ŕa ( ~ -o) 'eagle, vulture'.
