N'Ko (ߒߞߏ), also spelled Nko, is an alphabetic script devised by Solomana Kanté in 1949, as a modern writing system for the Manding languages of West Africa. The term Nko, which means I say in all Manding languages, is also used for the Manding literary standard written in the Nko script.
The script has a few similarities to the Arabic script, notably its direction (right-to-left) and the letters that are connected at the base. Unlike Arabic, it is obligatory to mark both tone and vowels. Nko tones are marked as diacritics.
