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.
Yemeni Arabic
Non-Arabic South Semitic languages indigenous to the region include several Modern South Arabian languages, such as the Mehri and Soqotri languages, which are not Arabic languages, but members of an independent branch of the Semitic family. Another separate Semitic family once spoken in the region is Old South Arabian; these became extinct in the pre-Islamic period with the possible exception of the Razihi. Some of these share areal features with Yemeni Arabic due to influence from or on Yemeni Arabic.
