Czech Sign Language is the sign language of the deaf community in the Czech Republic. It presumably emerged around the time of the first deaf school in Bohemia (1786). It belongs to the French sign-language family and is partially intelligible with French sign language.[2] Despite the similarity of oral Czech and Slovak, it is not particularly close to Slovak Sign Language.[citation needed]
^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.
