ピース

ぴーす
noun
piece; peace sign (V-sign)
1. peace sign, V-sign
The two-finger V-sign, above all when posing for photos (also ピースサイン). On its own, ピース does not mean peace as a state; that is 平和(へいわ).
Take a photo making a peace sign.
ピースで写(うつ)ろうよ。
Let's pose with a peace sign for the photo.
二本(にほん)の指(ゆび)でピースをする。
To make a peace sign with two fingers.
2. piece, component
An individual part or unit of something, such as a puzzle piece or a piece in a game.
One puzzle piece is missing.
I bought two slices of cake.
This information is the last piece of the puzzle. Everything connects now.

Usage

Sense 1 is most commonly used in ピースサイン or simply ピース (the V-sign gesture). In Japan, holding up two fingers in photos is ubiquitous and is called ピース.

Sense 2 is used for individual components, especially puzzle pieces. Also used as a counter-like suffix for sliced items (ケーキを二(に)ピース = two pieces/slices of cake).
