Origin:
late 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.
