Pronunciation

  • /identiˈdad/, [i.ð̞ẽn̪.t̪iˈð̞að̞][1]

Forms

identidad f (plural identidades)[1] 15th-century texts also have ydentidat and ydemptidat;[2][3] idemptidad is still found in a Mexican document of 1712.[2][3]

Etymology

It is borrowed from Late Latin identitas (“sameness”).[4][5][6] The Late Latin word was an artificial formation on idem (“the same”), made on the model of ens (“being”) and entitas (“entity”) to translate Ancient Greek ταυτότης (tautótēs, “sameness”).[4][5][7]

The same Latin word is French identité, Italian identità, Portuguese identidade and Catalan identitat.[8][1] Nascentes takes the Portuguese word from scholastic Latin by a semi-learned route.[9]

The Latin pronoun is a combination of is (“he, that”) with an enclitic particle -dem, which was cut out of the neuter form of the pronoun.[10] Wiktionary traces the second part to *izdim.[1]

Earliest recorded meaning

The DCECH's first record is Alfonso de la Torre's Visión deleitable (c. 1440), where Wisdom gives examples that are not ydentidat, strict sameness, but are close to true likeness.[4][2] The other 15th-century records are theological: Alonso de Madrigal and the 1494 translation of Bartholomaeus Anglicus, which speaks of the persons of the Trinity as united segund la identidad de su essençia “according to the identity of their essence”.[2]

Semantic evolution

The word stayed a term of philosophy and theology into the 16th century.[2] The Diccionario de Autoridades defines it as the reason why things that seem distinct are in fact one, and records the scholastic identidad de razón.[11] The Academy's dictionaries of the 19th century add identidad de persona, the legal fiction by which an heir is treated as the same person as the testator.[12][13]

In 1899 the Academy added the sense “being the same person or thing that is supposed or sought” and the mathematical identity.[14] The senses “the set of features that set a person or group apart” and “awareness of being oneself” are in the 2001 edition.[15] The identity papers of modern life, the carné de identidad and the documento nacional de identidad, belong to the sense “proof of being who one says”.[16] In the Americas the word is recorded from 1712, in a Mexican lawsuit.[3]

Timeline

  • c. 1440 – Alfonso de la Torre's Visión deleitable has ydentidat.[4][2]
  • 1494 – identidad in the translation of Bartholomaeus Anglicus, the first record without a later copy.[2]

  • 1817 – the Academy records identidad de persona as a legal term.[12]
  • 1884 – the Academy's dictionary derives it from Low Latin identitas.[17]
  • 1899 – the senses “being the one sought” and the mathematical identity are added.[14]
