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
Many Tunisian and Maghrebi words, like "qarnīṭ ("octopus")", have a Latin etymology. The dialects were later called Pre-Hilalian Arabic dialects and were used along Classical Arabic for communication in Tunisia. Also, Siculo-Arabic was spoken in several islands near Tunisia like Sicily, Pantelleria, and Malta and entered into contact with the Tunisian pre-hilalian dialects. Consequently, it ameliorated the divergence in grammar and structures of all the concerned dialects from Classical Arabic.
