Languages of Sudan
Approximately 70 languages are native to Sudan.
Sudanese Arabic is the most widely spoken language in the country. It is the variety of Arabic spoken throughout northern Sudan. It has much borrowed vocabulary from the local languages (El Rotana). This has resulted in a variety of Arabic that is unique to Sudan, reflecting the way in which the country has been influenced by both African and Arab cultures. Some of the tribes in Sudan still have similar accents to the ones in Saudi Arabia. Other important languages include Beja (AKA Bedawi) along the Red Sea, with perhaps 2 million speakers; Fur in the west (Darfur), with perhaps a million speakers; and the various Nubian languages along the Nile in the north, with half a million or so speakers. The most linguistically diverse region in the country are the Nuba Hills in Kordofan, inhabited by speakers of multiple language families, with Darfur and the Ethiopian-border regions being second.
Beja is the sole Cushitic language in Sudan. Arabic is Semitic, the Niger–Congo family is represented by many of the Kordofanian languages, and Indo-European by Domari (Gypsy) and English. Historically, Old Nubian, Greek, and Coptic (Egyptian) were the languages of Christian Nubia, and Meroitic the language of the Kingdom of Kush which conquered Egypt.
