forget it

Overlook it, disregard it. This colloquial imperative, dating from about 1900, is used in several ways. It can mean the same as “don’t mention it” or “you’re welcome,” as in, “‘Thanks for picking me up.’ ‘Forget it, it was no trouble.’” It also can mean “it won’t happen” or “it’s impossible,” as in “Find a parking space near the theater? Forget it!” These same meanings can be conveyed by forget about it, which, however, also may mean not to recall something and is not a cliché.

William Langland in Piers Ploughman held it up as a form of Christian charity to be practiced by all: “So will Cryst of his curteisye, and men crye hym mercy, bothe forgive and forgeter.” It appears in John Heywood’s 1546 collection of proverbs and was used by Shakespeare in at least four of his plays, including King Lear (4.7): “Pray you now, forget and forgive; I am old and foolish.” It remains current to the present day.
