An overview of the different varieties of Arabic; the Maghrebi varieties are shades of blue
Maghrebi Arabic (Western Arabic; as opposed to Eastern Arabic or Mashriqi Arabic) is an 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: ?; meaning "to rise or advance step by step"). This serves to differentiate the spoken vernacular from Modern 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.
Darija, Derija or Delja (Arabic: ?) means "everyday/colloquial language"; it is also rendered as ed-d?rija, derija or darja. It refers to any of the varieties of colloquial Maghrebi Arabic. Although it is also common in Algeria and Tunisia to refer to the Maghrebi Arabic varieties directly as languages, similarly it is also common in Egypt and Lebanon to refer to the Mashriqi Arabic varieties directly as languages. For instance, Algerian Arabic would be referred as Dzayri (Algerian) and Tunisian Arabic as Tounsi (Tunisian), and Egyptian Arabic would be referred as Masri (Egyptian) and Lebanese Arabic as Lubnani (Lebanese).
In contrast, the colloquial dialects of more eastern Arab countries, such as Egypt, Jordan and Sudan, are usually known as al-'?mm?ya (?), though Egyptians may also refer to their dialects as al-logha-d-darga.
The varieties of Maghrebi Arabic (Darija) have a significant degree of mutual intelligibility, especially between geographically adjacent ones (such as local dialects spoken in Eastern Morocco and Western Algeria or Eastern Algeria and North Tunisia or South Tunisia and Western Libya), but hardly between Moroccan and Tunisian Darija. Conversely, Moroccan Darija, Tunisian Derja and particularly Algerian Derja cannot be understood by Eastern Arabic speakers (from Egypt, Sudan, Levant, Iraq, and Arabian peninsula) in general as they derive from different substratums and a mixture of many languages (Berber, Latin (African Romance), Old Arabic, Turkish, French, Spanish, Mozarabic, Italian, and Niger-Congo languages). Some linguists like Charles A. Ferguson, William Marçais consider Maghrebi Arabic Darija an independent language.
Maghrebi Arabic continues to evolve by integrating new French or English words, notably in technical fields, or by replacing old French and Italian/Spanish ones with Modern Standard Arabic words within some circles; more educated and upper-class people who code-switch between Maghrebi Arabic and Modern Standard Arabic have more French and Italian/Spanish loanwords, especially the latter came from the time of al-Andalus. Maghrebi dialects all use n- as the first-person singular prefix on verbs, distinguishing them from Levantine dialects and Modern Standard Arabic.
Modern Standard Arabic ( al-Fus) is the primary language used in the government, legislation and judiciary of countries in the Maghreb. Maghrebi Arabic is mainly a spoken and vernacular language, although it occasionally appears in entertainment and advertising in urban areas of Algeria, Morocco and Tunisia. In Algeria, where Maghrebi Arabic was taught as a separate subject under French colonization, some textbooks in the language exist but they are no longer officially endorsed by the Algerian authorities. Maghrebi Arabic contains a Berber substratum, which represents the languages originally spoken by the native populations of the Maghreb prior to their adoption of Arabic. The dialect may also possess a Punic substrate. Additionally, Maghrebi Arabic has a Latin substratum, which may have been derived from the African Romance that was used as an urban lingua franca during the Byzantine Empire period.
Maghrebi Arabic speakers frequently borrow words from French (in Morocco, Algeria and Tunisia), Spanish (in Morocco) and Italian (in Libya and Tunisia) and conjugate them according to the rules of their dialects with some exceptions (like passive voice for example). Since it is not always written, there is no standard and it is free to change quickly and to pick up new vocabulary from neighbouring languages. This is somewhat similar to what happened to Middle English after the Norman conquest.
