From Middle English cauceweye, with the first element from Anglo-Norman, Old Northern French caucee or caucie, cauchie, from Vulgar Latin *calciāta (compare modern French chaussée from Old French chaucie, itself from the same source), either from Latin calx, calcis ("limestone"), or alternatively from Latin calciāre (“to stamp with the heels, tread”), from calx (“heel”). The second element corresponds to English way.
