アフロ・アジア語族
According to Peter Behrens (1981) and Marianne Bechaus-Gerst (2000), linguistic evidence indicates that the Kerma peoples spoke Afroasiatic languages of the Cushitic branch. They propose that the Nilo-Saharan Nobiin language today contains a number of key pastoralism related loanwords that are of proto-Highland East Cushitic origin, including the terms for sheep/goatskin, hen/cock, livestock enclosure, butter and milk. They argue that this in turn suggests that the Kerma population — which, along with the C-Group Culture, inhabited the Nile Valley immediately before the arrival of the first Nubian speakers — spoke Afroasiatic languages.
