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.
Levantine Arabic
The primary division between Arabic dialects in ancient times was between Northern Old Arabic, spoken in the southern Levant, and Old Hijazi, spoken in the northern, and later central Hijaz. The main representatives of Northern Old Arabic were Safaitic, Hismaic, and Nabataean Arabic. Tens of thousands of graffiti in the Safaitic and Hismaic scripts cover the deserts of southern Syria and present-day Jordan. The Safaitic inscriptions sometimes exhibit the article ʾ(l), a shared areal isogloss with the Arabic substrate of the Nabataean inscriptions. Many Safaitic inscriptions exhibit all of the features typical of Arabic. The Hismaic script was used to compose two long texts in an archaic stage of Arabic before the language acquired the definite article.
