This article is intended as a non-technical introduction to internal variation in Libyan Berber and its broader implications. Like Arab identity, Amazigh identity tends to be closely bound up with language. However, like Arabic, Berber is far from homogeneous, and mutual comprehensibility across different regions can be very limited. Understanding this cross-regional linguistic variation is important in order to predict, or plan, the future of Berber in Libya in a context of increasing institutionalisation and urbanisation.
