Comments:A Western isogloss. In Turkic the root has merged with *Kājnat 'wing' (see under *kēńa); this homonymy may have influenced Mong., where the stem qana(n) occasionally means 'wing, маховые перья'; but Mong. hardly < Turk., despite TMN 1, 416. In Mong. one has to suppose a reanalysis of *-t as a plural suffix.
