Etymology

The word is a straightforward compound of black + mail; the second element is not the modern postal sense but the older Scots and northern English male or mal, meaning a rent or tribute, itself from Old English māl “contract, terms”, which in turn hauls in Old Norse mál “agreement, lawsuit” and, further back, Proto-Germanic maþlą “gathering” and Proto-Indo-European med- “to measure or counsel”.

On the Anglo-Scottish Borders and in the Highlands the stuff was exacted by mounted freebooters who offered protection in exchange for produce or labour; the tribute was literally black because it was paid in goods rather than silver, and figuratively black because non-payment frequently ended in arson. Latin clerks labelled the two systems reditus nigri and reditus albi; locals simply called the extorted heap “black mail” and the legitimate coin “white rent”.

By 1826 the compound had slipped its geographical tether and was applied to any coerced payment, after which the original rural protection racket faded into footnote and the word settled into its modern career of threatening polite society from behind a letterbox.
