ナイル・サハラ語族
The Nubian languages are part of the Eastern Sudanic branch of the Nilo-Saharan languages. On the basis of a comparison with seventeen other Eastern Sudanic languages, Thelwall (1982) considers Nubian to be most closely related to Tama, a member of the Taman group, with an average lexical similarity of just 22.2 per cent.
