Comments:ТМС 2, 354. Doerfer MT 68-69 regards Manchu ferxe and Nan. perxe as borrowed from Mong., separating them from the rest of TM forms (derived ibid. from *puru- 'to crush' - ?). This all is clearly unacceptable, because in fact we are dealing with a very clear case of e/u alternation after a labial.
