A Sublexicon Approach to Morphological Dependencies
Guy Tabachnick
October 2021

Ackerman et al. (2009) and Ackerman and Malouf (2013) argue that the organization of morphological systems allows speakers to efficiently solve the Paradigm Cell Filling Problem: how to predict a word’s inflected form given some of its other forms. For example, a given word’s possessive suffix in Hungarian can be predicted in part by its phonology and by its exponent in forms like the plural. I propose a model in which this phonological and morphological predictability is encoded in formal, constraint-based grammars. In particular, I extend the sublexicon model (Gouskova et al., 2015), in which lexically specific behavior is handled using diacritics on lexical items. Thus, I treat the Paradigm Cell Filling Problem as a problem of finding correlations between diacritics in a given lexical entry, without relying on the storage of a paradigm’s output forms.
