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.
Yemeni Arabic
The Hadhrami dialect in many towns and villages in the "Wādī" (valley) and the coastal region is characterised by its pronunciation of the voiced palatal plosive (or affricate) (ج) as the semi-vowel (ي) ("y") (). In this it resembles some Eastern Arabian and Gulf dialects including the dialects of Basra in Iraq, Kuwait, Qatar, Bahrain and the dialects of the other Arab Emirates. In educated speech, (ج) is realised as a voiced palatal plosive () or affricate () in some lexical items.
