One who is fatigued suffers from a conscious and painful lack of strength as the result of some overtaxing; an invalid may be fatigued with very slight exertion; when one is wearied, the painful lack of strength is the result of long-continued demand or strain; one is exhausted when the strain has been so severe and continuous as utterly to consume the strength, so that further exertion is for the time impossible. One is fagged by drudgery; he is jaded by incessant repetition of the same act until it becomes increasingly difficult or well-nigh impossible; as, a horse is jaded by a long and unbroken journey.(noun)
