Peninsular Arabic

Peninsular Arabic are the varieties of Arabic spoken throughout the Arabian Peninsula. This includes the countries of Saudi Arabia, Yemen, Oman, United Arab Emirates, Kuwait, Bahrain, Qatar, Southern Iran, Southern Iraq and Jordan.

The modern dialects spoken in the Arabian Peninsula are closer to Classical Arabic than elsewhere in the Arab world. Some of the local dialects have retained many archaic features lost in other dialects, such as the conservation of nunation for indeterminate nouns. They retain most Classical syntax and vocabulary but still have some differences from Classical Arabic like the other dialects.

Varieties
Ingham and Holes both note the existence of two peninsular dialect groups: The following varieties are usually noted: The following table compares the Arabic terms between Saudi dialects of urban Hejazi and urban Najdi in addition to the dialect of the Harb tribe with its tribal area (Najdi and Hejazi parts) which shows a correlation and differences between those dialects:
 * 1) A southwestern dialect group that includes most of the dialects of South Arabia, stretching as far north as Al Bahah. Holes generalizes it to a "sedentary" or "peripheral" group that also includes dialects of historically sedentary populations on the Persian Gulf coast, such as Omani Arabic and Bahrani Arabic. These dialects share certain syntactic features with Modern South Arabian languages.
 * 2) A central-eastern dialect group originating in the center, that spread with the migration of Arab tribes. This group includes the dialects of most bedouin tribes in the peninsula, spanning an area extending from the Syrian Desert to the Empty Quarter. Its most notable examples are Najdi Arabic and Gulf Arabic.
 * Yemeni Arabic, displays a past conjugation with the very archaic -k suffix, as in southern Semitic languages. It has to be noted that the dialect of Aden has >  as in Cairo.
 * Hejazi Arabic, spoken in Saudi Arabia along the coast of the Red Sea, especially in the cities of Mecca and Jeddah. Strictly speaking, there are two distinct dialects spoken in the Hejaz region, one by the Bedouin rural population and another by the urban population in cities such as Jeddah, Mecca, Medina, Taif and Yanbu.
 * Najdi Arabic, spoken in the center of the peninsula in Saudi Arabia and is characterized by a shift of to  and affrication of  and  to  and, respectively, in certain contexts.
 * Dhofari Arabic, Spoken in Dhofar in southern Arabia, spoken in Yemen, Oman, and the surrounding regions.
 * Gulf Arabic (excluding Omani Arabic, Dhofari Arabic and Bahrani Arabic), spoken in the coast of the Persian Gulf.
 * Bahrani Arabic, spoken in Bahrain, Eastern Saudi Arabia, and Oman.
