Deutsche Gebärdensprache
The Polish Sign Language is the language of the Deaf community in Poland. It descends from German Sign Language. Its lexicon and grammar are distinct from the Polish language, although there is a manually coded version of Polish known as "System Językowo-Migowy" (SJM, or Signed Polish), which is often used by interpreters on television and by teachers in schools. In 2012, under the "Sign Language Act", the language received official status and can be chosen as the language of instruction by those who require it.
