While writing my immediately previous post on the Amazigh revival in Tunisia I stumbled across a link that involves several of this blog's odder little side interests: colloquial dialects, minority languages, and language generally: a series on "Amazigh Words in Libyan [Colloquial Arabic] Dialect." It's written in Arabic and this is actually installment number 12. I had trouble finding earlier examples on that site but an Arabic search (cut and paste ألكلمات الأمازيغية في اللهجة الليبية if you like) shows that it's apparently been appearing on several other websites as well.
UPDATE: As a commenter notes below, the article tends to find Amazigh sources for all sorts of Arabic words, some obviously from Italian. This is the kind of excessive linguistic chauvinism that led Qadhafi to insist Tamazight was just an Arabic dialect, and has led to other Arab nationalists claiming an Arabic origin for Tamazight, only reversed 180 degrees to find Amazigh roots everywhere. Still, it may be of interest.
