Mongolian Sign Language (Mongolian: Монгол дохионы хэл, Mongol dokhiony khel) is a sign language used in Mongolia. Ethnologue estimates that there were between 10,000 to 147,000 deaf people in Mongolia as of 1998[update]; however, it is not known how many of those are users of MSL.
Linda Ball, a Peace Corps volunteer in Mongolia, is believed to have created the first dictionary of MSL in 1995. In 2007, another MSL dictionary with 3,000 entries was published by Mongolia's Ministry of Education, Culture, and Science with assistance from UNESCO.
^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.
