Associate Professor of Linguistics Paul D. Fallon presented on June 12, 2023, at the 54th annual Conference on African Linguistics. His talk, titled “Three views of Proto-Cushitic: Theory, Heuristics, and Validity,” analyzed and compared three historical-comparative reconstructions of the Cushitic language family: the one by Aron Dolgopol’skij in 1973, one by Christopher Ehret in 1987, and one by M. Lionel Bender in 2020, each varying in scope, methodology and reconstructions, from a low of 15 consonants to a high of 87. The 46 Cushitic languages are a branch of the Afroasiatic phylum spoken in and around the Horn of Africa.
