Inferential-realizational morphology without rule blocks
The chapter outlines a formal theory of inferential-realizational morphology that eliminates (ordered) rule blocks. I show that rule blocks not only stand in the way of a more general treatment of variable morphotactics, but that they also artificially restrict the scope of Pāṇinian competition, effectively ruling out operation at a distance. Instead, it argues for a purely information-based model of global competition that reconciles competition with extended exponence by means of a distinction between realization and allomorphic conditioning. It shows, in particular, that arbitrary decisions with respect to this distinction can be eliminated, once Carstairs’s (1987) notion of Pure Sensitivity has been turned into a formal principle of our theory. Finally, the chapter shows how Information-based Morphology can account for symmetric cases of extended exponence by simultaneous introduction of exponents since the theory is able to capture many-to-many relations between form and function at the level of individual rules.
