Pronunciation

  • /autentiˈkaɾ/, [au̯.t̪ẽn̪.t̪iˈkaɾ][1]

Forms

autenticar (first-person singular present autentico, first-person singular preterite autentiqué, past participle autenticado)[1]

Etymology

The DLE takes it as borrowed from Medieval Latin authenticō (“to validate a record”), itself derived from authenticus (“authentic”).[2][1][3] Older editions of the Academy's dictionary, Moliner and Alonso derive it instead from Spanish auténtico with the verb suffix -ar.[4][5][6] The DCECH and the BDELC list it among the derivatives of auténtico.[7][8]

The Late Latin adjective, used of original documents, is a loan from Ancient Greek αὐθεντικός (authentikós, “having authority”), a derivative of αὐθέντης (authéntēs, “absolute master”).[7][9][10] The Medieval Latin verb meant “to validate a record”, “to declare canonical” and “to canonise”.[3] The same verb is Portuguese autenticar, French authentiquer and Italian autenticare.[1][11][12]

Earliest recorded meaning

Alfonso X's Siete Partidas (1256–1263) use the past participle of documents: a copy is valid if it is autenticado e firmado “authenticated and signed”.[6][13] The CDH has an earlier hit, escriptura cierta o autenticada, in the Aragonese Fueros de Aragón, dated 1247.[14]

Semantic evolution

In the General Estoria (1280) the teachers of Athens are asked to approve books por que ge los atenticassen, so that they could be read in the schools.[15] The DCECH explains the medieval spelling aténtico of the adjective as a hypercorrection.[7] Covarrubias (1611) defines the verb as giving authority to public documents, and Autoridades (1726) spells it authenticar and derives it from Greek.[16][17] The Academy's dictionary kept the definition “to authorise or legalise legally” from 1770 on.[18][19] The current DLE defines it by its synonym autentificar, recorded from 1893.[2][20]
