Past Participle: checkmated
Checkmate is derived from the Persian phrase "Shah Mat" (meaning the king is dead or defeated), which was adopted into Arabic as "Shah Mat" and then into Old French as "eschec mat". The term "check" comes from the Old French "eschec" (meaning to check or hinder), and "mate" is derived from the Persian "mat" (meaning dead or defeated). Together, they describe a situation in chess where the king is in a position to be captured and cannot escape, thus ending the game.
Imagine a king who is 'defeated' ('mat') and 'checked' ('eschec') in a game of chess — that's what checkmate means.
