アフロ・アジア語族
Peter Behrens (1981) and Marianne Bechaus-Gerst (2000) suggest that the ancient peoples of the C-Group and Kerma civilizations spoke Afroasiatic languages of the Berber and Cushitic branches, respectively. They propose that the Nilo-Saharan Nobiin language today contains a number of key pastoralism related loanwords that are of Berber or proto-Highland East Cushitic origin, including the terms for sheep/goatskin, hen/cock, livestock enclosure, butter and milk. This in turn, is interpreted to suggest that the C-Group and Kerma populations, who inhabited the Nile Valley immediately before the arrival of the first Nubian speakers, spoke Afroasiatic languages.
