reward: [14] Reward is ultimately the same word as regard, and indeed was originally used interchangeably with it. It came from rewarder, the Anglo-Norman version of Old French regarder, source of English regard. The modern meaning of reward, ‘recompense’, which goes back to the 14th century, presumably arose from the notion of ‘regarding’ someone with favour.
