Usage notes[edit]
Both fatigable and defatigable mean "able to be fatigued", but generally only fatigable is used in the medical sense (such as when referring to a reflex that is easily exhaustible/fatigable). Only in the word indefatigable (= in- + defatigable) does modern English regularly encounter a reminder of the rarer synonym of fatigable, but the word indefatigable tends to be used in a figurative sense (= remarkably persistent) rather than a literal/medical one (= remarkably immune to fatigue in the sense of having high physical fitness). The prefix de- in defatigable appears in its intensifying sense, not in its undoing sense.
