Árabe del Golfo
Gulf varieties' closest related relatives are other dialects native to the Arabian Peninsula, i.e. Najdi Arabic and Bahrani Arabic. Although spoken over much of Saudi Arabia's area, Gulf Arabic is not the native tongue of most Saudis, as the majority of them do not live in Eastern Arabia. There are some 200,000 Gulf Arabic speakers in the country, out of a population of over 30 million, mostly in the aforementioned Eastern Province.
