Why “indefatigability” is a great word
The quality of being incapable of weariness; an inherent and inexhaustible capacity for sustained effort. Formed within English from the adjective 'indefatigable' (from Latin indēfatīgābilis, from in- ("not") + dēfatīgāre ("to tire out")) + the noun-forming suffix '-ity'. Unlike "persistence," which focuses on continuing despite obstacles, or "stamina," which denotes a capacity for endurance, indefatigability implies an absolute, untiring force. It is the ceaseless motion of a river carving stone, the unblinking focus of a scholar's lamp in the small hours, and the steady, rhythmic breath of a long-distance runner in the predawn dark—a quiet defiance of the universe’s fundamental tendency toward exhaustion.
