Sign languages are full natural languages with their own grammar, unrelated to the spoken languages around them.
Czech Sign Language (Czech: Český znakový jazyk, ČZJ) 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. Both ČZJ and Slovak Sign Language are descendant from Austro-Hungarian Sign language.
