Peace and piece sound the same and share their first three letters. Peace with ea means calm, quiet and the end of fighting. Piece with ie means a part of something: a piece of cake, a piece of paper, a piece of music.
The memory line "a piece of pie" fixes the ie spelling, because pie has the same three letters. Peace keeps the ea of sea, and the sea can be calm.
This page gives both meanings, eight examples and 15 questions. Every answer says whether the sentence is about calm or about a part.
What each word means
peace
peace (noun): calm, quiet, and freedom from war or fighting. "Peace and quiet." "The two countries made peace."
piece
piece (noun): a part or portion of something. "A piece of cake." "A piece of music."
The rule
Peace is calm and no fighting
- Personal calm: leave me in peace, peace and quiet, at peace.
- Between countries or groups: peace talks, a peace agreement, world peace.
- The opposite is war or conflict: "The war ended and peace returned."
- Rest in peace is the phrase on a gravestone, with the ea spelling.
Piece is a part
- Piece of + uncountable noun: a piece of cake, a piece of advice, a piece of information.
- Piece of + singular countable noun: a piece of paper, a piece of music, a piece of furniture.
- Fixed phrases: in one piece means undamaged; piece by piece means gradually; a piece of your mind means an angry talk.
- The plural is pieces: "two pieces of cake".
The pie and sea test
- Piece shares its spelling with pie, and a piece of pie is a common phrase.
- Peace shares its spelling with sea, and the calm sea is a picture of peace.
- Does the sentence have a part or portion? Use piece with ie.
- Does the sentence have calm, quiet or war? Use peace with ea.
Traps in writing
- Would you like a peace of cake is wrong: the part of cake is a piece.
- World piece is wrong: the end of war is world peace.
- Rest in piece is wrong: the grave phrase is rest in peace.
- Give me a piece of your mind is the idiom, not peace. The meaning is an angry complaint.
