c. 1400, "to redress," from Middle French recompenser (14c.) and directly from Medieval Latin recompensare "to reward, remunerate," from Latin re- "again" (see re-) + compensare "balance out," literally "weigh together," from com "with, together" (see com-) + pensare, frequentative of pendere "to hang, cause to hang; weigh; pay" (from PIE root *(s)pen- "to draw, stretch, spin"). For the financial sense of the Latin verb, see pound (n.1). From early 15c. as "to compensate." Related: Recompensed; recompensing.
