Linguistics

Historically, the people of Nubia spoke at least two varieties of Nubian languages, a subfamily that includes Nobiin (the descendant of Old Nubian), Dongolawi, Midob and several related varieties in the northern part of the Nuba Mountains in South Kordofan. The Birgid language was spoken north of Nyala in Darfur, but became extinct as late as 1970. However, the linguistic identity of the ancient Kerma culture of southern and central Nubia (also known as Upper Nubia), is uncertain; some research suggests that it belonged to the Cushitic branch of the Afroasiatic languages, while more recent studies indicate that the Kerma culture belonged to the Eastern Sudanic branch of Nilo-Saharan languages instead, and that other peoples of northern or Lower Nubia north of Kerma (such as the C-Group culture and the Blemmyes) spoke Cushitic languages before the spread of Eastern Sudanic languages from southern or Upper Nubia.
