Wymysorys (Wymysiöeryś, pronounced [vɨmɨˈsʲøːrɪɕ, vɨmɨˈɕœ̯ɛrɪɕ]),[3][4] 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.

[5] The status of Wymysorys is complex because, genealogically, it belongs to the East Central dialect group of High German.

[5][8][9] The inhabitants of Wilamowice are thought to be descendants of German, Flemish and Scottish settlers who arrived in Poland during the 13th century.

[11]: 10 [13] The widespread bilingualism of the people saved most local residents from being forcibly resettled to Germany, but many of them stopped teaching their children their language or even using it in daily life.

Hejn ȧn cyryk was written in Wymysorys, based on the prose of J. R. R. Tolkien, and was staged, among others, at the Polish Theatre in Warsaw in February 2016.

Additionally, a new project called The Wymysiöeryśy Akademyj – Accademia Wilamowicziana or WA-AW was established under the "Artes Liberales" program at the University of Warsaw with the intention of creating a unified scholastic body for the study of the Wymysorys language.

It was not until the times of Florian Biesik, the first author of major literary works in the language, that a need for a separate version of a Latin alphabet arose.

[11]: 24  In recent times Józef Gara (1929–2013), another author of works in the local language, devised a distinct Wymysorys alphabet, consisting of 34 letters derived from the Latin script and mostly based on Polish as well: Wymysorys orthography includes the digraph "AO", which is treated as a separate letter.
