Penultimate lengthening in isiNdebele: A system and its variations

Abstract

Lengthening of the penultimate syllable in a word, phrase, or utterance is common across Bantu languages, especially in Eastern and  Southern Bantu languages. Despite the prevalence of the general phenomenon, there is significant cross-linguistic diversity in how PUL is  instantiated. The aim of this paper is to describe the PUL patterns and variation in isiNdebele, a Nguni language spoken in South  Africa. IsiNdebele is closely related to Zulu and frequently spoken in situations of intense contact with Zulu, but its realisation of  penultimate lengthening nevertheless shows important differences from what has been reported for Zulu and other Nguni languages. In  addition, penultimate lengthening in isiNdebele shows significant internal variation, both across speakers and across utterances  produced by the same speaker. This variation has implications for both phonological and syntactic analyses of this language: Many studies of phonological phrasing in other Nguni languages use penultimate length as the main phonetic cue for phrase boundaries, but a  strict correlation between PUL and phrasing cannot be confirmed for isiNdebele. Lengthening also depends on factors such as speech  rate, emphasis, and careful vs. casual speech.
