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
Berber languages while the Kabyles called theirs "Taqbaylit", and the inhabitants of the Siwa Oasis called their language "Siwi". In Tunisia, the local Amazigh language is usually referred to as "Shelha", a term which has been observed in Morocco as well. One group, the Linguasphere Observatory, has attempted to introduce the neologism "Tamazic languages" to refer to the Berber languages. Berber is a branch of the Afroasiatic language family. Since modern Berber languages are relatively homogeneous, the date of the Proto-Berber language from which the modern group is derived was probably comparatively recent, comparable to the age of the Germanic or Romance
