peace vs piece

These two words sound exactly the same but have completely different meanings.

  • peace — Peace' is a noun that refers to a state of calm, quiet, and the absence of conflict — for example, After the busy week, she was grateful for a moment of peace and quiet in the library.
  • piece — Piece' is a noun that refers to a part or portion of something — for example, She carefully cut the chart into equal pieces so each student could have one.

Memory rule: A simple trick: 'piece' contains the word 'pie', which reminds you it is about a portion or part of something. If you are describing calm or the absence of conflict, use 'peace'.
