(from the Saxon bana, a murderer), signifies destruction or overthrow. Thus, "I will be the bane of such a man," is a common saying. So, when a person receives a mortal injury by anything, we say, "it was his bane:" and he who is the cause of another man's death, is said to be le bane, i.e. a malefactor.
