    Defatigable means easily tired out, someone listless and unenergetic. Defatigable is a synonym of fatigable, which at first seems counter-intuitive. The meaning hinges on the prefix de-, which is usually used to coin a word that means the opposite action, such as bug and debug, or forest and deforest. However, the prefix de- may also mean thoroughly, or down to the bottom of something.
