Pronunciation

  • /rekuˈsaɾ/, [re.kuˈsaɾ][1]

Forms

recusar (first-person singular present recuso, first-person singular preterite recusé, past participle recusado)[1]

Etymology

It is borrowed from Latin recūsō (“to object, refuse”), a learned word taken over in the language of the law.[2][3][1] The Latin verb is formed from re- and causa (“cause; lawsuit”), like its siblings accūsō and excūsō, the sources of acusar and excusar.[4][5][6] Gómez de Silva glosses the prefix as “against, back”.[7]

The same Latin verb was borrowed as Portuguese recusar, Catalan recusar and Italian ricusare.[8][9][1] ruser is the inherited French outcome, with the loss of the medial consonant.[1]

The further origin of the Latin noun is unknown: Walde and Hofmann linked it to cūdō (“to strike”), an idea Wiktionary reports with the proposed root Proto-Indo-European *kewh₂- (“to strike”), while others doubt an Indo-European source.[6][1]

Earliest recorded meaning

The Corpus del Diccionario histórico has the participle in the Aragonese Fueros de Aragón of 1247, of a surety rejected because he is not an heir in the place.[10] In Castilian it appears before 1260 in Alfonso X's Espéculo, of a charter that can be challenged as forged, and around 1275 in his General estoria as recusolo “he refused it”.[10][11] From the start the verb thus meant to object to something or someone in a lawsuit.[10]

Semantic evolution

Corominas, who did not know the medieval records, dated the word from 1457 (Rodrigo de Arévalo), with a second record in the Nueva Recopilación of 1554, the date the Breve diccionario gives.[4][2] The Recopilación already used it of parties who object to members of the royal council, and Covarrubias in 1611 called recusar un juez a term of the courts.[12][13] In the Americas, colonial documents from 1537 on use it of a party rejecting a suspect judge.[14]

The Academy has given both senses since Autoridades: not to accept something, and in law to challenge a judge or other official so that he does not take part in the case.[12][3] From 1843 the Academy added that it applies also to witnesses, and in 1869 it added notaries.[15][16] Today the legal sense is defined as exercising a recusación, and Moliner extends it to experts and witnesses.[3][17]
