Bamako Sign Language (French: Langue des signes de Bamako), also known as Malian Sign Language, or LaSiMa (Langue des signes malienne) is a sign language that developed outside the Malian educational system, in the urban tea-circles of Bamako where deaf men gathered after work. It is used predominantly by men, and is threatened by the educational use of American Sign Language, which is the language of instruction for those deaf children who go to school.
^a Sign-language names reflect the region of origin. Natural sign languages are not related to the spoken language used in the same region. For example, French Sign Language originated in France, but is not related to French. Conversely, ASL and BSL both originated in English-speaking countries but are not related to each other; ASL however is related to French Sign Language.
^b Denotes the number (if known) of languages within the family. No further information is given on these languages.
