Quantified exponence constraints and the typology of exponence

Abstract

Both phonologically conditioned suppletive allomorphy (PCSA) and multiple exponence (ME) involve one-to-many mapping between morphosyntactic information and phonological representations. Though they are usually viewed as separate phenomena, the plural marking of Lower Jubba Maay exhibits properties of both PCSA and ME, indicating that they are inherently related. This paper argues that PCSA, ME, and other types of exponence can be analyzed in a unified way given two GEN functions and two novel exponence constraints, i.e. Max-∀LE(F) and Max-∃LE(F), which are used to quantify the number of exponents that are realized in the surface. The proposed mechanism can predict the full range of typology.
