Abstract
Distributed and multiple exponence create the possibility that a single lexeme may simultaneously belong to multiple inflection classes, e.g. a word form may contain prefixal, suffixal and prosodic inflectional exponents, each displaying allomorphic variation. This paper sketches an initial typology of the sorts of interactions that obtain between multiple inflection class systems, ranging from cross-classification to mutual implicature. Perhaps the most interesting systems are those in between, which give evidence both of the autonomy of the individual subsystems as well as greater or lesser degree of communication between them.
