The division of labor between representations and cophonologies in doubly conditioned processes in Amuzgo

This paper introduces a doubly conditioned phonological alternation in Amuzgo (OtoManguean) [Southern Mexico], where both a morphologically specific condition and a lexically specific condition must be met for a phonological alternation to surface. We interpret previous frameworks as making distinct specific predictions about the locality restrictions of the two conditioning factors in doubly morphologically conditioned phonology. We test these predictions against the Amuzgo case study.
