Comments:KW 157, Дыбо 8, Лексика 188 (Doerfer TMN 3, 527 regards the Turk.-Mong. match as "aus lautlichen Gründen mindestens unwahrscheinlich"), although phonetically the match is quite plausible. The Kor. form is not quite clear morphologically (kūmp(j)ǝŋ(i) < *kūŋ-p(j)ǝŋ, a compound with some unclear second component?), but semantically matches the other forms very well.
