It is ancestral to modern-day Nobiin and closely related to Dongolawi and Kenzi. It was used throughout the kingdom of Makuria, including the eparchy of Nobatia. The language is preserved in more than a hundred pages of documents and inscriptions, both of a religious (homilies, prayers, hagiographies, psalms, lectionaries), and related to the state and private life (legal documents, letters), written using an adaptation of the Coptic alphabet.
