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.
Sudanese Arabs
It was noted in the late 19th century that the Arabic spoken in Sudan still largely maintained grammatical and dialectical features similar to that introduced from the Arabian Peninsula in the 12th century, and as a result Sudanese Arabic is a form of pure or "archaic Arabic." This, among other features, serves to distinguish the Arabic spoken in Sudan from that of its neighbor, Egypt.
