Pronunciation

  • /xuɾaˈmento/, [xu.ɾaˈmẽn̪.t̪o][1]

Forms

juramento m (plural juramentos)[1] Old Spanish had juramento (also spelt iuramento) beside juramiento (iuramiento, yuramiento).[2][3][1]

Etymology

It is inherited from Old Spanish juramento, inherited from Late Latin iūrāmentum (“oath”).[4][1][5] Corominas dates it 1045 and lists it among the derivatives of jurar.[6] The same Latin word is Portuguese juramento, Galician xuramento, Asturian xuramentu, Catalan jurament, French jurement, Italian giuramento and Romanian jurământ.[7][8]

The Latin noun is formed from iūrō (“to swear, take an oath”) with the noun suffix -mentum.[1][5] The verb is formed from iūs (“law”).[9][10] De Vaan reconstructs a Proto-Italic noun *jowos “oath, law”, from a Proto-Indo-European word for “vital force, eternity”;[10][1] Wiktionary traces it to *h₂yew-.[10][1]

Earliest recorded meaning

Corominas's Breve diccionario dates the word 1045.[6] The DEMel's first record in a Spanish text is iuramiento in the Becerro of Benevívere (c. 1220–1230).[2] The early fueros use it for the oath of the parties: the Fuero de Cáceres (c. 1234–1275), still half in Latin, has si iuramento fizieren contra conceio “if they swear an oath against the council”.[11]

Semantic evolution

Alfonso X's laws speak of the yuramiento a sick man made to a priest.[3] Covarrubias in 1611 explains the juramento de calumnia from the Partidas, the oath the parties took that they did not go to law in bad faith.[12] Autoridades in 1734 defines the oath as calling on God as witness, either by naming him or through his creatures, and distinguishes the juramento asertorio, which affirms something present or past, and the conminatorio, which threatens harm.[13] The Academy's dictionary of 1817 adds the decisorio, execratorio, falso, judicial, promisorio and supletorio oaths.[14]

The proverb si el juramento es por nos, la burra es nuestra, por Dios (about how easily people swear to their own advantage) is in Domínguez and in the Academy's edition of 1869.[15][16] The sense “curse, swear word” entered the Academy's dictionary in 1899;[17][18] Moliner glosses it as a blasphemy or angry imprecation.[17][18] In Panama juramento a la bandera is the civic pledge of loyalty to the nation.[4] The word is recorded in Puerto Rico in 1512, in a judicial deposition.[19]
