Proto-Berber language reached the stage where these different branches of this language family evolved. From that perspective, Proto-Berber was the first Berber stage to depart from Proto-Afrosiatic in the eighth millennium. It was restructured several times during the almost 10,000 years that separated it from its modern shape, which has preserved few relics. Roger Blench (2018) suggests that Proto-Berber speakers 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
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,
