The West Slavs are Slavic peoples speaking West Slavic languages. These are the current Slovaks, Czechs, Kashubians, Poles and Sorbs. The northern or Lechitic group includes, along with Polish, the Kashubian and extinct Polabian and Pomeranian languages. The languages of Upper and Lower Lusatia have features in common with both the Lechitic and the Czecho-Slovak group.
