Deserving to receive a reward or recognition for something good or valuable that has been done.

Rewardable → It is formed from "reward" (from Old French *recompenser*, meaning to give back or compensate) and "-able" (meaning capable of). The word "rewardable" means capable of being rewarded or deserving of a reward.
Think of something that is 'capable of being compensated' — that's what rewardable means.
