Wymysorys language

Wymysorys (Wymysiöeryś), also known as Vilamovian or Wilamowicean, is a West Germanic micro-language actively used in the small town of Wilamowice, Poland (Wymysoü in Wymysorys), on the border between Silesia and Lesser Poland, near Bielsko-Biała. It is considered an endangered language. At present, there are probably between 70 and 100 native users of Wymysorys, virtually all bilingual; the majority are elderly.
