supererogatory

adjective, su·per·erog·a·to·ry ˌsü-pər-i-ˈrä-gə-ˌtȯr-ē

(Late Latin: supererogatio "payment beyond what is due or asked", from super "beyond" and erogare "to pay out, expend" [from ex "out" and rogare "to ask"]) is the performance of more than is asked for; the action of doing more than duty requires. In ethics, an act is supererogatory if it is good but not morally required to be done. It refers to an act that is more than necessary, when another course of action—involving less—would still be an acceptable action. It differs from a duty (which is an act that would be wrong not to do), and from acts that are morally neutral. Supererogation may be considered as performing above and beyond a normative course of duty to further benefits and functionality.
