Word Origin and History for forever and a day
Idioms and Phrases with forever and a day
forever and a day
For a very long time, as in He's been working on that book forever and a day. This hyperbolic expression probably originated as a corruption of the now obsolete for ever and ay. Shakespeare used it in The Taming of the Shrew (4:4): “Farewell for ever and a day.” Today it is mainly a substitute for “very long time.” [c. 1600]
Incessantly, ceaselessly, as in Will this racket never end? It's been going on forever and a day. [Colloquial; first half of 1900s]
