The Optimization of Codas via Onset-Nucleus Sharing: Evidence from a Developing Second Language System

Abstract

Using sociolinguistic methodology for data collection and analysis, this study investigates the variable development of English word-final voiceless stops (codas) by Brazilian Portuguese (BP) speakers. In particular, based on phonetic evidence and along the lines of Goad (2002), the study provides evidence for an intermediate developmental stage in the acquisition of English cadas by BP speakers, characterized by the phenomenon of Onset Nucleus Sharing (ONS). Under this analysis to the syllabification of syllablefinal consonants, it is assumed that the potential coda (C) syllabifies as an onset (O) and, in order to be licensed, some of its features spread into the following empty nucleus (N) in order to optimize the syllable shape of the emerging grammar (i.e., to render a highly marked ONC syllable - e.g., [ʃipʱ] - into a relatively less marked ON.ON structure-e.g.
