词源
late 16th cent. （as a military term denoting a strip of land along the outer edge of a ditch, protected by a parapet）： from French, from Italian corridore, alteration （by association with corridore 'runner'） of corridoio 'running-place', from correre 'to run', from Latin currere. The current sense dates from the early 19th cent.
