Minimization of Allomorphy

In §2 .2 .5 , we saw that the dispersion theory of contrast needs to be supplemented by a theory of morphophonological alternations. In Prince and Smolensky (1993) the extent of variation between allomorphs is limited by faithfulness constraints because these constraints require surface realizations of a morpheme to be similar to the underlying form of the morpheme. But faithfulness constraints are fundamentally incompatible with dispersion constraints because they also effectively favor maintaining contrasts, a function which is taken over by MAXIMIZE CONTRASTS in dispersion theory.
