A trump card or suit has been designated a higher rank than usual for the purposes of the game being played and will triumph over others of normally equal value.
Trump is a distortion of the word triumph.
If you add up the number of letters in the names of the cards, the total is fifty-two, the same as the number of cards in the deck.
