Etymologically

deuce

Etymology and origin of the English word deuce

Pronunciation

  • IPA: /djuːs/ (UK); /duːs/ (US)[1]

Etymology

It is inherited from Middle English deus, borrowed from Middle French deus (“two”),[2][3][4][5][6] from Latin duōs, the accusative of duo “two”.[2][3][4][5][6] The spelling with -ce reflects the voiceless pronunciation, as in dice.[4] The mild oath the deuce “the devil” is probably related, perhaps through Low German daus “two at dice; bad luck”.[2][4][6]

Earliest recorded meaning

The two-spot in a game of dice (about 1475);[3][4] a throw of two (1519).[7][3]

Semantic evolution

The tennis sense, a score of 40 all after which two successive points are needed to win, dates from 1598 and was influenced by French à deux de jeu.[3][7][4] Because two was the lowest and unluckiest throw at dice, deuce came to mean bad luck or mischief (1651) and then the devil, used in mild oaths such as what the deuce (by 1710).[7][4] The resemblance to Latin deus “god” may have helped.[4] A playing card with two pips is a deuce from 1680.[7]
