Wymysorys (
Wymysiöerys), 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-Biala. 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.
