"day's unpaid labor due to a lord by vassals under French feudal system" (abolished 1776), mid-14c., from Old French corvee (12c., Modern French corvée), from Late Latin corrogata (opera) "requested (work)," from fem. past participle of Latin corrogare, from assimilated form of com "with" (see com-) + rogare "to ask," apparently a figurative use of a PIE verb meaning literally "to stretch out (the hand)," from PIE *rog-, variant of the root *reg- "move in a straight line."
