Identity relations in paralelistic models: morphology and phonology

Abstract

This paper discusses aspects of brazilian portuguese morphology-phonology interface within the framework of optimality theory. The paper rewiews the notion of faithfulness in three parellel models: (a) classic optimality (Prince & Smolensky, 1993), (b) correspondence (McCarthy & Prince, 1995; Benua, 1995) and (c) sympathy (McCarthy, 1998). While McCarthy's (1998) sympathy theory is a response to explaining phonological opacity within parallel optimality theory, it is demonstrated that non-concatenative morphology process, like truncation and lexical blend, also can be described with this framework.
