Abstract
This paper deals with the historical relations between dialects of Boni, a Cushitic language of Kenya and Somalia. Boni forms the subject of Volume 10 of the Language and Dialect Atlas of Kenya (Heine, Bernd & Wilhelm J. G. Möhlig. 1982. Boni Dialect. Language and Dialect Atlas of Kenya: Vol. X ed. by Bernd Heine and Wilhelm J. G. Möhlig. Berlin: Dietrich Reimer.Google Scholar logo with link to Google Scholar). Heine presents evidence for three subgroups within Boni, as well as several areas of convergence between dialects belonging to different proposed subgroups. In reviewing his evidence, I find that two of the three splits are not supported by the data, and therefore his conclusions on convergence must also be reinterpreted. Given the presence of numerous intersecting isoglosses, the tree diagram is an inappropriate model for describing the relations between Boni dialects, and I turn to Historical Glottometry (Kalyan, Siva & Alexandre François. 2018. Freeing the Comparative Method from the Tree Model: A Framework for Historical Glottometry. Let’s Talk About Trees: Tackling Problems in Representing Phylogenic Relationships Among Languages ed. by Ritsuko Kikusawa & Lawrence Reid, 59–89.
