Berber languages evidence from medieval Berber manuscripts that all indigenous North Africans from Libya to Morocco have at some point called their language "Tamaziɣt". The name "Tamaziɣt" is currently being used increasingly by educated Berbers to refer to the written Berber language, and even to Berber as a whole, including Tuareg. In 2001, Berber became a constitutional national language of Algeria, and in 2011 Berber became a constitutionally official language of Morocco. In 2016, Berber became a constitutionally official language of Algeria alongside Arabic. The term "Berber" has been used in Europe since at least the 17th century and is still used
Proto-Berber language A.D. Blench (2018) notes that Berber is considerably different from other Afroasiatic branches, but modern-day Berber languages displays low internal diversity. The presence of Punic borrowings in Proto-Berber points to the diversification of modern Berber language varieties subsequent to the fall of Carthage in 146 B.C.; only Zenaga lacks Punic loanwords. Additionally, Latin loanwords in Proto-Berber point to the breakup of Proto-Berber between 0-200 A.D. During this time period, Roman innovations including the ox-plough, camel, and orchard management were adopted by Berber communities along the "limes", or borders of the Roman Empire. This resulted in a new trading culture involving
