In 1690, the expression "to coin a phrase" began circulating in English taverns and public houses. The phrase was derived from the prevalent coinage of money and implied the invention of a new term or saying, akin to minting a new coin. Quickly gaining popularity through word of mouth, it humorously connected the literal minting process with the creative crafting of expressions. The phrase evolved to symbolize the era's burgeoning creativity and wit, expanding beyond its literal origins.
