Peace of Mind or Piece of Mind – Quick Answer
✅ The correct phrase is “peace of mind.”
It means a sense of calm, security, or freedom from worry.
Examples:
- “Knowing my family is safe gives me peace of mind.”

🚫 “Piece of mind” is a common mistake. However, in rare cases, it’s used humorously or to mean “a portion of someone’s thoughts,” as in:

- ✖ Piece of mind = incorrect (unless joking or using the idiom “give someone a piece of your mind”)
The Origin of “Peace of Mind or Piece of Mind”
The phrase “peace of mind” dates back to the 16th century, derived from the Old French pais (peace) and Latin pax, meaning “tranquility” or “freedom from disturbance.”
Writers used it to describe emotional calmness or spiritual balance — a state where the mind is at rest.
The confusion began much later, as “peace” and “piece” became homophones (sounded alike). This caused people to write “piece of mind” by mistake, thinking it made sense. But historically and grammatically, “peace” is the only correct version.
