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.
Varieties of Arabic
Modern languages have also typically provided a significant number of new words, and have sometimes also influenced pronunciation or word order. Examples are Turkish and English in Egypt, French in North Africa and Syria, English and French in Lebanon, and English and Hebrew in Israel. However, a much more significant factor for all five dialect groups is, as Latin among Romance languages, retention (or change of meaning) of the form of Classical Arabic used in the Quran.
