verbing
verbing n the act or practice of using a noun as a verb, such as ‘medal’ to mean “to win a medal” (CED)
Verbing is a time-honored way of coining new words out of old ones, the etymological process of conversion (or functional shifting). Sometimes it’s also a kind of word play (anthimeria), as in Shakespeare’s King Richard the Second when the Duke of York says, “Grace me no grace, and uncle me no uncles.”
