Where this word comes from
From black + mail (“a piece of money”). Compare Middle English blak rente (“a type of blackmail levied by Irish chieftains”). The word is variously derived from the tribute paid by English and Scottish border dwellers to border reivers in return for immunity from raids and other harassment. This tribute was paid in goods or labour, in Latin reditus nigri (“black mail”); the opposite is blanche firmes or reditus albi (“white rent”), denoting payment by silver. McKay derives it from two Scottish Gaelic words blàthaich, pronounced (the th silent) bl-aich, "to protect" and màl (“tribute, payment”). He notes that the practice was common in the Scottish Highlands as well as the Borders. More likely, from black + Middle English mal, male, maile (“a payment, rent, tribute”), from Old English māl (“speech, contract, agreement, lawsuit, terms, bargaining”), from Old Norse mál (“agreement, speech, lawsuit”); related to Old English mæðel (“meeting, council”), mæl (“speech”), Gothic 𐌼𐌰𐌸𐌻 (maþl, “meeting place”), from Proto-Germanic *maþlą (“gathering, agreement”), ultimately from Proto-Indo-European *med- (“to give advice, measure”). From the practice of freebooting clan chieftains who ran protection rackets against Scottish farmers. Black from the evil of the practice. Expanded c. 1826 to any type of extortion money. Compare silver mail (“rent paid in money”) (1590s); buttock mail (“fine imposed for fornication”) (1530s, Scottish).
To extort money or favors from (a person) by exciting fears of injury other than bodily harm, such as injury to reputation, distress of mind, false accusation, etc.
