Associate Professor of Linguistics Paul D. Fallon presented the paper “Lexical Innovation in Cushitic: Fictitious Family or Fragile Unity?” at the 2017 Annual Meeting of the Linguistic Society of America (LSA), Austin, TX, on Jan. 6, 2017. Using the strict criteria of Orel & Stolbova applied to Christopher Ehret’s reconstruction of Proto-Cushitic, he found that shared lexical innovation alone cannot be used as a diagnostic of Cushitic languages.
