O alinhamento relacional e o mapeamento de ataques complexos em português

Abstract

In this paper, we analyze the mapping of tautosyllabic consonantal clusters in Portuguese in light of the Optimality Theory. It is observed that consonantal clusters in the same syllable are well-formed when the sonority distance between the consonants is +3, for instance, in the sequences pr and bl in words like prato (‘dish’) and blusa (‘blouse’). In clusters with a sonority distance lesser than +3, such as sp (sport) and pt (ptose, ‘ptosis’), there is a vowel before the sibilant or between the consonants, [i]sport e p[i]tose. To account for these facts it is proposed a constraint hierarchy in order to regulate the sonority distance between segments within a complex onset: *ONS DIST. It is also proposed a constraint that controls the sonority distance between segments in adjacent syllables: DIST -x. We argue that the interaction among these constraints and faithfulness constraints – OUTPUT-CONTIGUITY (no internal epenthesis), DEP (no epenthesis) e MAX (no deletion) – is responsible for the faithful mapping of the consonantal clusters and for the occurrence of vocalic epenthesis.
