masc nom sg of kusala (adj); masc nom sg of kusala (noun)
Etymology. Root √kus (to be skilled, expert); cognate with Sanskrit kuśala. The word carries the sense of skillfulness and moral worth together in Buddhist ethics: a kusala action bears fruit in better rebirth. Related to Greek χρήσιμος (chrēsimos, useful) through the proto-sense of fit, apt; kusala thus represents the convergence of practical competence and ethical rectitude.
