The Malagasy Sign Language (Malagasy: Tenin'ny Tanana Malagasy, abbreviated TTN) is a sign language used for communication among hearing impaired people in Madagascar.
An estimated 110,000 to 170,000 people (or 1% of the population of Madagascar) are deaf.
Malagasy Sign Language is similar to Norwegian Sign Language because the first deaf school in Madagascar was founded in 1960 by the Malagasy Lutheran Church with the assistance of a number of Norwegians, including Norwegian teachers.
[1] Seven deaf schools in Madagascar are sponsored by Evangelical Lutherans.
