Pronunciation

  • /djuˈɛt/, /duˈɛt/[1]

Etymology

It is borrowed from Italian duetto (“short piece for two voices”),[2][3][4][5] a diminutive of duo (“duet”),[3][6][4] which comes from Latin duo (“two”),[5][7] from Proto-Indo-European *dwo- (“two”).[8][3] The Shorter Oxford allows a borrowing from German Duett as well,[9] and Ayto says English took the word either directly from Italian or perhaps through German;[7] the OED records the German word from 1710.[2] Etymonline names French duet as the immediate source.[8] The English ending matches the suffix -et.[2][10]

Earliest recorded meaning

A musical composition for two performers: 1725, in Lewis Theobald's Harlequin Sorcerer.[2] Barnhart dates the form duet to 1740, replacing duetto (1724),[4] and Merriam-Webster to about 1735.[6]

Semantic evolution

The Italian form duetto was used in English for about a hundred years from the 1720s,[7] and both duet and duetto were preceded in English, as in Italian, by duo.[4] From 1749 the word could mean simply a pair of people or things;[2] from 1761 it was used of any sound or action likened to a duet, especially one made by two together;[2] later it was used of a dance by two people as well.[2][6] The verb, to perform a duet, appears in 1822 in a letter of Byron's.[4][2][8] Etymonline records the diminutive duettino, a short and simple duet, by 1839.[8]
