COMMENT: Except for the metathesis in PA (*χimi-r < *miχi-r), all correspondences are regular. It is possible that the word is an old derivate (with the instrumental prefix *m-) from the verb *=ĭχ_V 'to carry' (q.v.). In this case Ub. mǝχ-mǝ́q is the only trace of this verbal root (otherwise completely lost) in WC.
