IPA: /ˈtʃɛs.mən/
KK: /ˈtʃɛsˌmæn/
A piece used in the game of chess, such as a pawn, knight, bishop, rook, queen, or king.
Each player starts with sixteen chessmen on the board.
Chessman → The word is formed from "chess" (from Old French *esches*, meaning the game of chess) and "man" (from Old English *mann*, meaning a person). A chessman refers to a person or piece involved in the game of chess.
Think of a 'person' ('man') who plays the game of 'chess' — that's what a chessman is.
