The origin of the name beskydy has not been conclusively established. A Thracian or Illyrian origin has been suggested, however, as yet, no theory has majority support among linguists. The word appears in numerous mountain names throughout the Carpathians and the adjacent Balkan regions, like in Albanian bjeshkë. The Slovak name Beskydy refers to the Polish Bieszczady Mountains, which is not a synonym for the entire Beskids but one single range, belonging to the Eastern Beskids. According to another linguistic theory, it may be related to Middle Low German beshêt, beskēt, meaning watershed.
