Prekmurje Slovene, also known as the Prekmurje dialect, East Slovene, or Wendish, is a Slovene dialect belonging to a Pannonian dialect group of Slovene. It is used in private communication, liturgy, and publications by authors from Prekmurje. It is spoken in the Prekmurje region of Slovenia and by the Hungarian Slovenes in Vas County in western Hungary. It is closely related to other Slovene dialects in neighboring Slovene Styria, as well as to Kajkavian with which it retains a considerable degree of mutual intelligibility and forms a dialect continuum with other South Slavic languages.
