The Slovak Sign Language is the sign language of the deaf community in Slovakia. It belongs to the French sign-language family. Bickford (2005) found that Slovak, Czech, and Hungarian Sign formed a cluster with Romanian, Bulgarian, and Polish Sign.
Despite the similarity of oral Slovak and Czech, SSL is not particularly close to Czech Sign Language.
^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.
