Tunisian Arabic

Tunisian Arabic, or simply Tunisian (Arabic: تونسي, romanized: Tūnsi), is a variety of Arabic spoken in Tunisia. It is known among its 13 million speakers as Tūnsi, [ˈtuːnsi] ^ⓘ "Tunisian" or Derja (Arabic: الدارجة; meaning "common or everyday dialect") to distinguish it from Modern Standard Arabic, the official language of Tunisia. Tunisian Arabic is mostly similar to eastern Algerian Arabic and western Libyan Arabic.

As part of the Maghrebi Arabic dialect continuum, Tunisian merges into Algerian Arabic and Libyan Arabic at the borders of the country. Like other Maghrebi dialects, it has a vocabulary that is predominantly Semitic and Arabic with a Berber, Latin and possibly Neo-Punic substratum. Tunisian Arabic contains Berber loanwords which represent 8% to 9% of its vocabulary. However, Tunisian has also loanwords from French, Turkish, Italian and the languages of Spain and a little bit of Persian.

Multilingualism within Tunisia and in the Tunisian diaspora makes it common for Tunisians to code-switch, mixing Tunisian with French, English, Italian, Standard Arabic or other languages in daily speech. Within some circles, Tunisian Arabic has thereby integrated new French and English words, notably in technical fields, or has replaced old French and Italian loans with standard Arabic words. Moreover, code-switching between Tunisian Arabic and modern standard Arabic is mainly done by more educated and upper-class people and has not negatively affected the use of more recent French and English loanwords in Tunisian.

Tunisian Arabic is also closely related to Maltese, which is a separate language that descended from Tunisian and Siculo-Arabic. Maltese and Tunisian Arabic have about 30 to 40 per cent spoken mutual intelligibility.
