What does checkmate mean?
Checkmate is the decisive end of a chess game: the moment a player's king is attacked and no legal move can save it. Beyond the board, it has become a vivid metaphor for any irreversible defeat — a negotiation lost, an argument won outright, a rival thoroughly outmaneuvered. The word entered English from Old French 'echec mat', itself from Persian 'shāh māt', meaning 'the king is helpless or dead'. Its long journey through Arabic, Latin, and French reflects the ancient spread of chess itself across cultures. Checkmate carries connotations of finality and skillful triumph; unlike a stalemate, which leaves both sides without victory, a checkmate crowns a clear winner. It remains one of the most widely recognized terms from the game of kings.
A position in chess in which a player's king is in check with no possible move to escape, ending the game.
"Fischer forced a beautiful checkmate in just seventeen moves."
Often preceded by verbs like 'deliver' or 'force'.
To place an opponent's king in checkmate, winning the chess game; figuratively, to defeat someone completely.
"He checkmated his opponent on the thirty-second move."
Standard plural used when referring to multiple instances of checkmate positions.
"The grandmaster's book catalogued hundreds of famous checkmates."
The word 'checkmate' traces back over a thousand years to the Persian phrase 'shāh māt' — meaning 'the king is helpless' — making it one of the oldest borrowed phrases still used daily in English.

Etymology of checkmate
Checkmate comes ultimately from the Persian phrase shāh māt, meaning 'the king is helpless' or 'the king is defeated'. It passed into Arabic, then into Old French as echec mat, entering Middle English around the fourteenth century alongside the game of chess itself. The first element gave English the word 'check', and the same Persian root also produced 'exchequer' via its association with counting boards resembling chessboards.
