Comments:See SKE 68 (in Kor. cf. also igɨrǝ-ǯida 'to act up, put on airs'). One of the numerous common Altaic verbs of emotion. Semantic match between Turkic, Mongolian and Japanese is straightforward ("to be angry, indignant"). In TM one has to suppose a shift > "to be insolent, obscene" > "sing obscene songs, blackguard" (Manchu), with further generalization > "sing" in other languages. In Korean we see a different semantic shift > "to put on airs, be haughty" > "to overcome".
