Title: Lexical storage and the cyclic reapplication of phonological processes
Date/Time: Monday, Apr 8, 5-6:30p
Location: 32-D831
This talk seeks to describe and explain the peculiar properties of phonological processes applying in cyclic domains smaller than the word, i.e. in sublexical domains. In stratal-cyclic phonological frameworks such as Lexical Phonology and Stratal Optimality Theory, such processes are assigned to the highest stratum in the grammar: the stem level. To characterize the stem-level syndrome, rule-based Lexical Phonology imposed special conditions on rule application at the stem level: stem-level rules were claimed to exhibit stratum-internal cyclic reapplication, to be structure-preserving, and to undergo blocking in nonderived environments. English stress assignment provides a classic example of cyclic reapplication within the same stratum: in a word like [WL [SL [SL imàgin-] átion-] less-ness], foot creation applies twice in the two inner stem-level cycles, and does not apply in the outer word-level domain.
The Lexical Phonology approach to the stem-level syndrome made a number of incorrect predictions. Notably, English has a large set of phonological processes whose domain excludes word-level suffixes, but which nonetheless do not show cyclic reapplication, structure preservation, or blocking in nonderived environments. The GOAT split in the London vernacular is a particularly salient example. In contrast, the stem-level syndrome has altogether dropped off the agenda in current optimality-theoretic frameworks relying on output-output correspondence. Such frameworks do not recognize the notion of cyclic domain, and so cannot sort phonological processes into classes according to domain size. This stance is also unsatisfactory insofar as it fails to account for striking generalizations: in particular, cyclic reapplication within the same stratum is only found at the stem level.
This talk outlines an alternative approach to the stem-level syndrome, where the special properties of stem-level phonological processes emerge from more fundamental grammatical mechanisms. I propose that the distinguishing trait of stem-level linguistic expressions is that they are stored nonanalytically, i.e. as whole output forms generated by the stem-level morphology and phonology. In contrast, word-level and phrase-level constructs are either not stored, or stored analytically (i.e. decomposed as strings of stem-level pieces). Given independently motivated assumptions about morphological blocking, together with the input-output faithfulness technology of Optimality Theory, these postulates about lexical storage make accurate predictions about the behaviour of stem-level phonological processes. Notably, cyclic reapplication turns out to be closely correlated with neutralization (Chung’s Generalization).
