The term "trump card" originated from the popular card game, Trump, which was played during the 15th century in Europe. In this game, each player was dealt a set of cards, and one card was designated as the "Trump" card, which had the highest value and could take any other suit. The concept of the trump card was then incorporated into other card games such as Bridge, Whist, and Poker, where it served as a powerful tool to defeat opponents. In these games, the trump card takes precedence over other cards of the same suit and helps the player to win the game. The term "trump card" entered into the English language during the 19th century and has since been widely used in various contexts, such as metaphorically as a hidden advantage or secret weapon that can turn the tables in one's favor. In modern usage, the term "trump card" has become a part of popular culture, appearing in movies, books, and other forms of media.
