Finland-Swedish Sign Language

Finland-Swedish Sign Language (FinSSL; Finlandssvenskt teckenspråk, Suomenruotsalainen viittomakieli) is a moribund sign language in Finland. It is now used mainly in private settings by older adults who attended the only Swedish school for the deaf in Finland (in Porvoo, Borgå), which was established in the mid-19th century by Carl Oscar Malm but closed in 1993. However, it has recently been taught to some younger individuals. Some 90 persons have it as their native language and it is spoken by around 300 people in total.

History
The first deaf school in Finland was founded in 1846 by Carl Oscar Malm, who was deaf himself. Since the closure of the deaf school in Borgå in 1993, the future of the language has been uncertain. Many families with deaf children have emigrated to Sweden because of the decision. The language is considered severely endangered according to UNESCO's criteria.

Since 2015, Finland-Swedish and Finnish sign languages have been recognized as separate languages in Finnish legislation, as the new sign language act was adopted in the parliament. However, the scientific consensus has been since 2005 that the two sign languages are distinct.

Differences from Finnish Sign
Through contacts between Swedish deaf individuals and Finland-Swedish deaf individuals, the Finland-Swedish sign language has borrowed many words from Swedish sign language. Additionally, the visual phonology with facial expressions follows the sounds of the Swedish language.
