Pronunciation

  • /ˈduke/, [ˈd̪u.ke][1]

Forms

duque m (plural duques, feminine duquesa, feminine plural duquesas)[1] Old Spanish first wrote the word duc, the French form;[2] duque is recorded from about 1295.[3][2] The feminine is duquesa, recorded in the Gran Conquista de Ultramar of about 1295.[4][5]

Etymology

It is borrowed from Old French duc (“duke”).[3][5][6][1] The Tentative Dictionary of Medieval Spanish gives Old Occitan duc as the source instead.[7] The Old French word is itself from Latin dux (“leader, guide”), the title given in the Late Roman Empire to high military and civil officials of the provinces.[3][8][9] The feminine duquesa follows duchesse, a derivative of the French noun.[5]

The Latin noun is formed from dūcō (“to lead”), which de Vaan traces to Proto-Indo-European *deuk- (“to draw”).[10][11] The same Latin word gave Italian duca, French duc and, through Venetian, Italian doge.[12][1] Spanish has the learned doublet dux beside it.[3][1]

Earliest recorded meaning

DEMel lists the Liber Regum (1194–1211) as the earliest text with the word.[2] The French form duc is recorded from 1220, and duque from about 1295.[3] In Alfonso X's histories (1270–1284) the word names the general of an army and the holder of the title: the Estoria de España has a duc of King Theoderic, the General estoria the duques who ruled Israel.[13]

Semantic evolution

The first sense, “commander of an army”, matches the Late Latin title;[14][13] Alfonso X's Partidas, as Covarrubias quotes them, explain the word as “leader and guide of an army” whose office was granted by the emperor.[14][13] Autoridades defines the duke as the holder of the dignity that carried the honour of Grandee of Spain, and records a second, unrelated-looking sense: a fold that women made in their mantle by pinning it to the hair.[15] The Academy kept “general of an army” and “military and political governor of a province” as old senses; the DLE now marks both as disused and defines the title as the highest rank of nobility, just above marquis.[5][16] Domínguez in 1846 recorded the phrase vivir como un duque “to live like a duke”, i.e. in comfort.[17] In Mexico, Cuba and Bolivia duque is the number two in some games.[18]
