blackmail verb

blackmailer noun

Etymology

from black (the color) and mail "rent, payment," from Old English māl "agreement," of Norse origin

Word Origin

The word blackmail has no connection at all with the postal system. In the 16th and part of the 17th centuries, the area along the border between England and Scotland was not usually protected by the officials on either side. Landholders were beset not only by outlaws but also by their own chieftains, who told them that in return for payment they would not be raided. In Scotland mail means "rent" or "payment." This word comes ultimately from an Old Norse word māl meaning "agreement" or "speech." The mail delivered by a letter carrier originally meant "sack, bag," and referred to the sack in which letters were carried; it is hence completely distinct in origin from the mail of blackmail.
