Morphotactics in an information-based model of realisational morphology

Abstract

In most recent work, Crysmann and Bonami (2012) suggest to reconcile the insights of inferential-realisational morphology (Anderson, 1992; Stump, 2001; Brown and Hippisley, 2012) with the full typology of variable morphotactics: situations where the expression of analogous feature sets can appear in various positions in the string. The authors proposed to account for these facts by importing, into HPSG, a variant of Paradigm Function Morphology (Stump, 2001) where realisation rules are doubly indexed for linear position and paradigmatic opposition. In this paper we first introduce more empirical challenges for theories of morphotactics that neither PFM nor the reformist approach of Crysmann and Bonami (2012) can accommodate. We then argue for a reappraisal of methods for morph introduction, and propose a new approach that replaces stipulation of classes of paradigmatic opposition with a general distinction between expression and conditioning (Carstairs, 1987; Noyer, 1992) which greatly expands the scope of Pāṇini’s Principle.
