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.
