A person who illegally obtains money or favors from someone by threatening them or using force.
The police arrested the extortioner who had been threatening local businesses for money.
Extortioner → It is formed from "ex-" (meaning out of or from) and "torquere" (meaning to twist or turn), combined with the agent suffix "-er" (meaning one who). An extortioner is one who twists or turns a situation to extract money or favors from others, often through coercion.
Think of someone who 'twists' ('torquere') a situation to get something 'out of' ('ex-') another person — that's why an extortioner is someone who forces others to give up their money or favors.
