mortify

Mortify once actually meant "put to death", but no longer. Its "deaden" sense is most familiar to us in the phrase "mortifying the flesh", which refers to a custom once followed by devout Christians, who would starve themselves, deprive themselves of every comfort, and even whip themselves in order to subdue their bodily desires and punish themselves for their sins. But the most common use of mortify today is the "humiliate" sense; its connection with death is still apparent when we speak of "dying of embarrassment".
