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
Names of the Berber people as Numidians and later as Mauri in classical antiquity. These are umbrella terms that would include populations whose self-designation was a variety of tribal names, although Strabo asserts that "Mauri" was also used indigenously. The "Libu" of ancient Egyptian sources, eponymous of the name "Libya" may also have been an early Berber or Proto-Berber population. The term "Berber" is a variation of the Greek original word "barbaros" ("barbarian"), earlier in history applied by Romans specifically to their northern hostile neighbors from Germania (modern Germany) and Celts, Iberians, Gauls, Goths and Thracians. The variation is a French one when spelled "Berbère"
