Hejaz
Historically, the Hejaz has always seen itself as separate from the rest of Saudi Arabia. The Hejaz is the most populated region in Saudi Arabia; 35% of all Saudis live there. Hejazi Arabic is the most widely spoken dialect in the region. Saudi Hejazis are of ethnically diverse origins.
Hadhrami Arabic
Hadhrami Arabic, or Ḥaḍrami Arabic, is a variety of Arabic spoken by the Hadhrami people ("Ḥaḍārima") living in the Hadhramaut. It is also spoken by many emigrants, who migrated from the Hadhramaut to the Horn of Africa (Somalia and Eritrea), East Africa (Comoros, Zanzibar, Kenya, Tanzania, and Mozambique), Southeast Asia (Indonesia, Malaysia, Brunei and Singapore) and, recently, to the other Arab states of the Persian Gulf.
