Establishing Order in Type-Based Realisational Morphology

Recent years have witnessed a renewal of interest in variable morph ordering, the situation where the position of a morph in the word is not constant. These situations present a challenge to extant inferential-realisational approaches to morphology (Stump, 2001), insofar as these adopt implicitly or explicitly an a-morphous approach to morphological composition (Anderson, 1992). In this paper we will first review the typology of known variable morph ordering phenomena in inflection. We then argue that the challenges can be met by making a distinction between paradigmatic opposition classes and syntagmatic position classes, and show that this distinction can readily be implemented in HPSG while keeping the amorphous assumption.
