Orthography
There are three currently active proposals for a Nubian alphabet: based on the Arabic script, the Latin script, and the Old Nubian alphabet. Since the 1950s, Latin has been used by 4 authors, Arabic by 2, and Old Nubian by 1, in the publication of various books of proverbs, dictionaries, and textbooks. For Arabic, the extended ISESCO system may be used to indicate vowels and consonants not found in the Arabic alphabet itself.
