The place names of the Maghreb come from a variety of origins, mostly Arabic and Berber, but including a few derived from Phoenician, Latin, and several other languages. This is well illustrated by the three largest cities of Algeria, for instance: Algiers from Arabic al-jazā'ir "the islands", Oran from wahran from Berber wa-iharan "place of lions" and Constantine (Arabic Qasantina قسنطينة) from the Latin name of the emperor Constantine. For a Phoenician name, one has to look a little harder; but take, for instance, Jijel, shortened from Latin Igilgili, from Phoenician i gilgilt "Island of the Skull" (according to Lipinski.)
Given the fact that Arabs founded very few cities in the regions they conquered, a large portion of cities in Arab countries have non-Arab etymologies. Many places, however, have had their names changed and "Arabized." The following toponymic elements are common in place names in the Maghreb:
