Berber languages suggests that the C-Group population — which, along with the Kerma culture, inhabited the Nile valley immediately before the arrival of the first Nubian speakers — spoke Afro-Asiatic languages. Roger Blench (2018) suggests that Proto-Berber speakers had spread from the Nile River valley to North Africa 4,000-5,000 years ago due to the spread of pastoralism, and experienced intense language leveling about 2,000 years ago as the Roman Empire was expanding in North Africa. Hence, although Berber had split off from Afroasiatic several thousand years ago, Proto-Berber itself can only be reconstructed to a period as late as 200 A.D. Blench
Proto-Berber language in relation to its determinants (agentive subject, object…) whose syntactic functions are insured by casual elements including the casual affix (ergative) that indicates, as needed, the agent or the subject. Similar elements attested in Cushitic, Chadic and Omotic, and remains preserved in Semitic drove Diakonoff to postulate the same type of syntactic construction for proto-Semitic et proto-Afroasiatic (cf. Diakonoff, 1988, 101 ; cf. equally Allati, 2008, 2011a, 2012). Proto-Berber language Proto-Berber is the reconstructed proto-language from which the modern Berber languages stem. Proto-Berber was an Afroasiatic language, and as such, its descendant Berber languages are cousins to the Egyptian language,
