Saudi Arabia
The official language of Saudi Arabia is Arabic. The three main regional variants spoken by Saudis are Hejazi Arabic (about 6 million speakers), Najdi Arabic (about 8 million speakers), and Gulf Arabic (about 0.2 million speakers). Saudi Sign Language is the principal language of the deaf community. The large expatriate communities also speak their own languages, the most numerous of which are Tagalog (700,000), Rohingya (400,000), Urdu (380,000), Egyptian Arabic (300,000), and Indonesian (250,000).
Varieties of Arabic
An important factor in the mixing or changing of Arabic is the concept of a prestige dialect. This refers to the level of respect accorded to a language or dialect within a speech community. The formal Arabic language carries a considerable prestige in most Arabic-speaking communities, depending on the context. This is not the only source of prestige, though. Many studies have shown that for most speakers, there is a prestige variety of vernacular Arabic. In Egypt, for non-Cairenes, the prestige dialect is Cairo Arabic. For Jordanian women from Bedouin or rural background, it may be the urban dialects of the big cities, especially including the capital Amman. Moreover, in certain contexts, a dialect relatively different from formal Arabic may carry more prestige than a dialect closer to the formal language—this is the case in Bahrain, for example.
