Teschener Mundarten
The Cieszyn Silesian dialect is spoken by around 200,000 people in the Czech Republic. It is mainly used by the Polish minority, but also by some people of Czech and Slovak ethnicity in the same area. The Czech government considers the Cieszyn Silesian dialect to be a variety of Polish, and Polish is a recognised minority language in the Karviná and Frýdek-Místek Districts, where the dialect is natively spoken.
