pizarra

slate (metamorphic rock); blackboard, chalkboard; whiteboard; scoreboard; dashboard (panel with instruments or controls facing the driver in a vehicle)

First attested in 1475. Inherited from Old Spanish piçarra, from Basque, further derivation uncertain. * Perhaps from Basque *lapitz-arri (literally “slate stone”), from lapitz (“slate”) + arri (“stone”), with initial la- misinterpreted as the feminine singular article la. * Perhaps from Basque *pitzarri, blend of pitzatu (“to break into pieces”) + arri (“stone”).
