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.
