What Does Perish the Thought Mean?
Perish the thought is a standalone phrase used to tell someone not to even think about a negative thing; a wish that something negative mentioned will never happen; a wish that a thought will never become fact or reality.

Origin of Perish the Thought
The idiom perish the thought originated in the theater, specifically in Colley Cibberโs 1700 adaptation of William Shakespeareโs Richard III.
While Shakespeare wrote the original play, Cibber famously rewrote large portions of it to make it more dramatic for 18th-century audiences. In Act 5, Scene 3, as King Richard wakes from a nightmare on the eve of battle, he cries out:
“Perish the thought! No, never be it said, That Fate itself could awe the Soul of Richard.”
Cibberโs version of the play was so popular that it actually replaced Shakespeareโs original on the English stage for nearly 150 years. This is almost certainly how the phrase entered the general household vocabulary. It was a “movie line” that everyone knew.
Transition to “High Art”
Nearly 50 years after Cibber’s play premiered, the phrase was picked up in “high art” circles. It appeared in print in 1748 within the libretto for Handelโs oratorio Joshua, written by Thomas Morell:
“It never shall be said that our allies in vain implorโd our aid. Perish the thought!”
By the late 1800s, the phrase was in regular everyday use. The word perish is used here in its literal sense, meaning to die or cease to exist, essentially telling a negative idea to “die” before it can become a reality.
