Kashubian or Cassubian (Kashubian: kaszëbsczi jãzëk, Polish: język kaszubski) is a West Slavic language belonging to the Lechitic subgroup along with Polish and Silesian lect. Although often classified as a language in its own right, it is sometimes viewed as a dialect of Pomeranian or as a dialect of Polish. This singable and poetic text was posted on Lyricstranslate. I wouldn't be surprised if the song is sung in Polish dialects, or rather the song could be translated in various dialects as well. [Boreč]
