Proto-Turkic: *Koma
Meaning: 1 concubine 2 wives of the same husband
Russian meaning: 1 наложница 2 жены одного мужа по отношению друг к другу
Turkish: kuma 1, 2
Karaim: quma 1
Comments: Turk. > MMong. (MA, LHa) quma id. (although Doerfer TMN 1, 415 suggests the opposite direction of loan - which is dubious because of the isolated nature of the MMong. form).
