ABSTRACT
This chapter illustrates how the different modules of grammar can be integrated into a coherent whole through constraint-based theories such as Optimality Theory (OT), with a particular focus on phonological alternations that are conditioned by morphological processes. It provides a brief overview of Stratal OT. The chapter presents a reanalysis of Gorgia Toscana (GT). OT, both in its mainstream parallel version and the stratified version, is a theory of phonological computation that can be grouped with other theoretical frameworks that assume a modular grammatical architecture. Stratal OT is a constraint-based model of phonology that draws upon research carried out in the Lexical Phonology and Morphology (LPM) programme. Morpho-phonological processes operate on three morphological constituents in Stratal OT, namely root, stem and word. In addition to phonological processes that are driven by morphological operations like diminution, Stratal OT is particularly well suited to accounting for phonological processes that are triggered by the concatenation of words into a phrase.
