Комментарий: 3d class in all class-distinguishing languages. Cf. also Lezg. Khl. t:ur. External parallels make us believe that the Tab. form is the most archaic (muč:̌ur < *moc̣:ʷi-r with -r originally as a suffix); but reasons for loss of *mo- in all other languages are unclear (such a loss is regular only for Lezg.). We may deal here with a secondary contamination with a quite different EC root, reflected in Bezht. c̣oro 'scoop', Cham. č̣ora 'mug'. See Талибов 1980, 264.
