Word Originlate 16th century (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 century.
