Usage
"Uncouth though he was, (Geoffroi) le Brun was at least more sophisticated an operator than some of his neighbours. Most of them simply mulcted, amerced, plundered, ravaged, and otherwise terrified their trembling feudal subordinates. Le Brun, advised by a monk skilled in public relations, proceeded more cautiously. He wrote them long letters explaining why what he did was entirely necessary and in their best interests. Only then did he mulct, amerce, plunder, ravage and otherwise terrify them." — Smallweed; The Guardian (London, UK); Jan 28, 1995.
"But only three in all God's universe Have heard this word thou hast said, -- Himself, beside Thee speaking, and me listening! and replied One of us ... that was God, ... and laid the curse So darkly on my eyelids, as to amerce My sight from seeing thee." — Elizabeth Barrett Browning; Sonnets From the Portuguese; 19th C.
