Phonological and perceptual factor symbiosis in loanword adaptation

Abstract

This paper examines the two-way interaction of perceptual and production factors in the light of resolving French and English loan structures in Kirundi. The investigation is framed within the view that loanword adaptation results from attempts to match the non-native perception of the L2 input, within the confines of the L1 grammar. Neither a purely perceptual nor a purely grammatical account can explain the facts. Based on 239 French and 44 English corpora of loans, this study examines loanword adaptation at both the phonemic and the phonotactic levels. We prove how the constraint-ranking Optimality Theory (OT) can account for the phonological adaptations of loans but with limitations. The adaptation cannot be fully understood unless perceptual similarity and auditory factors are integrated in the grammar. This study enriches our understanding of the role of perceptual similarity and perceptual salience in phonology and their relationship to constraint ranking.
