Maghrebi Arabic (Western Arabic; as opposed to Eastern or Mashriqi Arabic) is a vernacular Arabic dialect continuum spoken in the Maghreb region, in Morocco, Algeria, Tunisia, Libya, Western Sahara, and Mauritania. It includes Moroccan, Algerian, Tunisian, Libyan, and Hassaniya Arabic. Speakers of Maghrebi Arabic are primarily Arab-Berbers who call their language Derdja, Derja, Derija or Darija (Arabic: الدارجة‎; meaning "common or everyday language"). This serves to differentiate the spoken vernacular from Standard Arabic. The Maltese language is believed to be derived from Siculo-Arabic and ultimately from Tunisian Arabic, as it contains some typical Maghrebi Arabic areal characteristics.
