1. Struck dumb, insensible, or motionless with fear or confusion. His speech was full of such fire and anger that I was rendered all-a-mort for a few moments afterward.
2. In a dying or half-dead state; depressed or dejected, as in one who feels half dead. Possibly a corruption of "alamort," meaning the same, or a reference to a "mort," the sound from a hunter's horn to signal the death of an animal being hunted. I'm all-a-mort these past two days; I know not if I shall live beyond the week.
