Polish Sign Language (Polish: Polski język migowy, PJM) is the language of the deaf community in Poland.
[citation needed] 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.
Around that time, the Instytut Głuchoniemych (Institute for the Deaf-Mute) was founded by Jakub Falkowski, who began teaching deaf children after meeting a deaf boy by the name of Piotr Gąsowski.
[2] In 1879, its first dictionary was published by Józef Hollak and Teofil Jagodziński, titled "Słownik mimiczny dla głuchoniemych i osób z nimi styczność mających"[3] ("The Mimic Dictionary for the Deaf-Mute and Persons Having Contact with Them").
