Wymysorys (Wymysiöeryś, pronounced [vɨmɨˈsʲøːrɪɕ, vɨmɨˈɕœ̯ɛrɪɕ]), also known as Vilamovian, Wilamowicean, or Wilmesaurisch, is a West Germanic language spoken by the Vilamovian ethnic minority in the town of Wilamowice, Silesian Voivodeship, Poland (Wymysoü in Wymysorys), on the border between Silesia and Lesser Poland, near Bielsko-Biała. It is considered an endangered language, possibly the most so of any of the Germanic languages.
