German Sign Language
In Switzerland, the language is called "Gebärdensprache" ("sign language") if a distinction from other languages is not required. Some sources call it "Natürliche Gebärden" or "Natürliche Gebärdensprache", or Swiss Sign Language ("Langage gestuel suisse"). The former just means 'natural sign', like those for "sleep" or "eat", in contrast to "Abstrakte Gebärden" 'conceptual sign', and so the term is no longer used. Most English sources today uses the term "German-Swiss Sign Language" or "Swiss-German Sign Language".
