King
/kɪŋ/The piece that must be protected from checkmate; the objective of the entire game.
Each side has one king, which moves one square in any direction and cannot move into check. Losing the ability to escape check (checkmate) ends the game. The name has stayed remarkably stable across chess history, tracking royal titles in nearly every language the game has touched.
Etymology
Unlike most other pieces, the king's identity has never changed: in Sanskrit chaturanga it was raja, simply "king," and Persian shatranj called it shah, again "king" or "monarch." It is this Persian shah that, filtered through Arabic and Old French échec, gave English both "check" and "chess" itself — meaning the entire game is, linguistically, named after this one piece under attack. Because capturing the king outright would end the game too abruptly and undramatically, Persian rules added the refinement that a king could never be moved into check or left in check, which is why in modern chess the king is never actually captured — the game ends the moment checkmate is unavoidable. This single continuous naming thread, from raja to shah to modern translations of "king" in dozens of languages, makes the king the most etymologically stable piece on the board.
