Hejazi Arabic
Hejazi Arabic or Hijazi Arabic ( '), also known as West Arabian Arabic, is a variety of Arabic spoken in the Hejaz region in Saudi Arabia. Strictly speaking, there are two main groups of dialects spoken in the Hejaz region, one by the urban population, originally spoken in the major cities of Jeddah, Mecca and Medina, and another by the Bedouin or rural populations. However, the term most often applies to the urban variety which is discussed in this article.
Tunisian Arabic
By then, Tunisian Arabic reached nationwide usage and became composed of six slightly different but fully mutually intelligible dialects: Tunis dialect, considered the reference Tunisian dialect; Sahil dialect; Sfax dialect; southwestern dialect; southeastern dialect and northwestern dialect. Older dialects became less commonly used and began disappearing. Consequently, Tunisian became the main prestigious language of communication and interaction within the Tunisian community and Tunisia became the most linguistically homogeneous state of the Maghreb. However, Berber dialects, Libyan and Algerian Arabic as well as several Tunisian dialects like the traditional urban woman dialect, Judeo-Tunisian Arabic or even several Tunisian structures like "lā" noun"+š", also practically disappeared from Tunisia.
