IPA: //ˈɡreɪmeɪl//
KK: /ˈɡreɪˌmeɪl/
A strategy used in legal cases where someone threatens to disclose confidential information to avoid prosecution or to gain an advantage.
The defendant used graymail to pressure the government into dropping the charges against him.
Graymail is a blend of 'gray' (from Old English 'grǣg', meaning of a color between black and white) and 'mail' (from Old French 'maille', meaning a bag or pouch). The term refers to a type of extortion where a person threatens to reveal damaging information unless paid, often in a context that is morally ambiguous, hence the 'gray' area of legality or ethics.
Think of the color 'gray' representing something morally ambiguous and 'mail' as a form of communication or delivery. This helps you remember that 'graymail' involves delivering threats in a morally gray area.
