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.
Semitic languages
In Arab-dominated Yemen and Oman, on the southern rim of the Arabian Peninsula, a few tribes continue to speak Modern South Arabian languages such as Mahri and Soqotri. These languages differ greatly from both the surrounding Arabic dialects and from the (unrelated but previously thought to be related) languages of the Old South Arabian inscriptions.
