The Jen language cluster: A comparative analysis of wordlists

Abstract

A lexicostatistical analysis divides the Jen language cluster into two primary branches Burak-Loo-Maghdi-Mak and Kyak-Moo-Leelau-Tha-Doso-Dza. This is also supported by extensive isoglosses, replacing the older Bikwin-Jen division at least for purposes of genetic classification. For vowels, a 9-vowel system is reconstructed, but its 3-way height contrasts appear unstable in some languages, either in the central vowels or in the front and back vowels. Front and back vowels also vary widely with diphthongs. Prosodic features of nasalisation, tone, and breathiness are reconstructed, with nasalisation developing in more roots in the second primary branch. For consonants, the large inventory includes particularly unstable coronals, and development of voiceless approximants in Doso-Dza. The comparative evidence is conflicting as to whether labialised and palatalised structures are secondary modifications or onset sequences, suggesting the need for a variationist approach. Overall, riverine Jen varieties Tha, Doso, Dza show unusually extensive sound change, in contrast to the more phonologically stable Bikwin varieties. Applications to orthography development include the need to represent implosives and /r/ in languages other than Dza, where they have been lost, and the need to represent vowel nasalisation and /h/ in languages of the second branch only. Initial stem consonant alternations seen in both nouns and verbs need more investigation in Jen languages.
