Comments:EAS 65, Poppe 27, Lee 1958, 113, АПиПЯЯ 35, 281, Дыбо 13. Mong. *ǯoɣog 'meal; pleasure' was alternatively compared (see KW 477) with PT *juba- 'to enjoy; console' (see ЭСТЯ 4, 240-241) - which is not excluded, but does not weaken the rest of the etymology. The derived form with a labial suffix must have already existed in PA (Kor. čap- = ТМ *ǯe-p- = PJ *da-pa-). The root (one of a number of common Altaic monosyllabic roots) is quite valid, despite Doerfer's (TMN 4, 193) critical attempts. .
