The word Catalan derives from the territory of Catalonia, itself of disputed etymology. The main theory suggests that Catalunya (Latin <answer>Gathia Launia</answer>) derives from the name Gothia or Gauthia ("Land of the Goths"), since the origins of the Catalan counts, lords and people were found in the March of Gothia, whence Gothland > Gothlandia > Gothalania > Catalonia theoretically derived.
