Additionally, a script known as Masaba or Ma-sa-ba was developed for the language beginning in 1930 by Woyo Couloubayi (c.1910-1982) of Assatiémala. Named for the first characters in Couloubayi's preferred collation order, Masaba is a syllabary which uses diacritics to indicate vowel qualities such as tone, length, and nasalization. Though not conclusively related to other writing systems, Masaba appears to draw on traditional Bambara iconography and shares some similarities with the Vai syllabary of Liberia and with Arabic-derived secret alphabets used in Hodh (now Hodh El Gharbi and Hodh Ech Chargui Regions of Mauritania). As of 1978, Masaba was in limited use in several communities in Nioro Cercle for accounting, personal correspondence, and the recording of Muslim prayers; the script's current status and prevalence is unknown.
