Tunisian Arabic
Classical Arabic began to be installed as a governmental and administrative language in Tunisia that was called then "Ifriqiya" from its older name "Africa" during the Muslim conquest of the Maghreb in 673. The people of several urban cities were progressively influenced by Arabic. By the 11th century, through contact of local languages such as African Romance or Berber with Classical Arabic, some urban dialects appeared in the main coastal cities of Tunisia. The dialects were slightly and characteristically influenced by several common Berber structures and vocabulary like negation because Tamazight was the language of contact for citizens of that period. The new dialects were also significantly influenced by other historical languages.
