Teschener Mundarten
The Cieszyn Silesian dialect or Teschen Silesian dialect (Cieszyn Silesian: "cieszyńsko rzecz"; or ""; ) is one of the Silesian dialects. It has its roots mainly in Old Polish and also has strong influences from Czech and German and, to a lesser extent, from Vlach and Slovak. It is spoken in Cieszyn Silesia, a region on both sides of the Polish-Czech border. It remains mostly a spoken language. The dialect is better preserved today than traditional dialects of many other West Slavic regions.
