Labial palatalization in Nguni and Sotho languages: internal and external evidence

Abstract

The process of labial palatalization in Nguni and Sotho languages is considered, with a view to establishing the non-phonological status of this process within the modern languages. A variety of evidence types is considered, both internal and external, including the non-application of palatalization in loanwords, non-transfer in second language learning, unconditioned use in specialized language, and limits in experimental conditions. The non-phonological course of processual breakdown in the speech of Zulu- and Sotho-speaking aphasics is considered in detail.
