A trump is a playing card elevated above its usual rank in trick-taking games, typically an entire suit nominated as the trump suit, which outranks all other suits. The concept first appeared around 1420 with the invention of Tarot cards, when the Duke of Milan ordered a deck featuring 16 trumps depicting Greek and Roman gods, and the word itself derives from the Italian trionfi (meaning "triumph"), first documented in English in 1529. In modern games, the trump suit can be fixed (as in Spades), determined by random draw (Bezique), or chosen through bidding (contract bridge and Skat). Playing a trump on a trick led by another suit is called trumping or ruffing, and a higher trump played in response is an overruff. Interestingly, a contemporary South German game called Karnöffel introduced partial trumps (chosen suits) with variable powers—a feature that persists in its family but is never seen in Tarot games, which use a permanent 22-card trump suit.
