It's important to note that DGS is a distinct language with its own grammar, vocabulary, and structure. While it shares some similarities with other sign languages, it's not mutually intelligible with them.
There are also regional variations within DGS, just like spoken languages. For example, there are differences between DGS in the north and south of Germany.
While DGS is the primary sign language, there are smaller communities of other sign languages used in Germany, such as:
* Austrian Sign Language (ÖGS)
* Swiss German Sign Language (DSS)
* International Sign (IS) - This is often used in international settings, like conferences or gatherings of Deaf individuals from different countries.
It's also worth mentioning that there are regional dialects within DGS, just like there are regional dialects of spoken German.
