You can't unring a bell.
Meaning
Once something has been said or done, its impact or consequences cannot be undone or reversed.
Origin
Imagine a medieval town, perhaps hushed in the early hours. Then, a sudden, urgent peel from the church bell shatters the quiet, signaling fire or invasion. Once that heavy clapper has struck, once the resonant sound has begun its journey through the air, there is no stopping it. No one can reach out and pull the sound back into the bell, can they? This very literal, undeniable truth—that an action, once initiated, cannot be undone—gave birth to this stark proverb, a vivid reminder from an age when sounds had a powerful, irreversible presence, warning us that some deeds, like a ringing bell, simply cannot be silenced or forgotten.
Examples
- I deeply regret spreading that rumor, but you can't unring a bell, so now I just have to face the repercussions.
- The politician's gaffe during the live interview caused irreparable damage to his campaign; after all, you can't unring a bell.
