Etymology
the word 'fatigability' is a modern scientific and medical term constructed from classical elements. its core, 'fatig-', descends from the latin verb fatigare, meaning 'to weary or tire out', which itself may have older, uncertain origins. this root is combined with the noun-forming suffix '-ability', derived from latin -abilitas, which indicates a quality, capacity, or tendency. therefore, the term's literal construction means "the capacity or tendency to be tired," a meaning it retains directly in contemporary usage to describe a physiological or clinical susceptibility to fatigue.
