Language/Czech-sign-language/Pronunciation/Alphabet
Czech Sign Language is the sign language of the deaf community in the Czech Republic. It probably appeared during the time of the first school for the deaf in Bohemia (1786). It belongs to a family called French Sign Language, and it is partially intelligible with French Sign Language. Although it is similar to Slovak, it is not particularly close to it either because they have different languages and also because there are many dialects in each country.
This shows the fact that not all sign languages are universal, so all sign languages are different. Sign language barriers exist because there are no universal rules and guidelines for how a specific individual signs their words or phrases. Moreover, with such a variety of languages in the world today, it would be impossible to create a global system of signs without privileging certain cultures over others.
