Pronunciation

  • /unifiˈkaɾ/, [u.ni.fiˈkaɾ][1]

Forms

unificar (first-person singular present unifico, first-person singular preterite unifiqué, past participle unificado)[1]

Etymology

It is borrowed from Late Latin ūnificō (“to make one”), a compound of ūnus (“one”) and faciō (“to make”).[2][1][3] Medieval Latin glossaries explain the verb as “to make one”, and Niermeyer gives it the senses “to unify, merge”.[4][5] The DRAE of 2001 and Moliner instead analyse it as a Spanish formation from uni- or uno with -ificar.[6][7] Corominas lists it among the compounds of uno, with a first record in Lope de Vega.[8]

Earliest recorded meaning

The earliest record in the CDH is in Alfonso de la Torre's Visión deleitable (c. 1430–1440, in a 15th-century copy), where the winds are said to unite all things: los quales unifican todas las cosas “which unify all things”.[9]

Semantic evolution

Lope de Vega's La Dorotea (1632) uses it in a philosophical sense, of the form unificando el todo con las partes “unifying the whole with its parts”, the passage Autoridades quoted in 1739 for the sense “to make one thing or a whole of many, by uniting or mixing them”.[9][3] The Academy's 1869 edition added “or by reducing them to one kind”, and the DLE now adds a second sense, making separate things form one organisation or serve a common end.[10][2] In the Americas it is recorded from 1808, in Uruguay.[11]

Timeline

  • c. 1430–1440 – first record, in Alfonso de la Torre's Visión deleitable.[9]
  • 1632 – Lope de Vega's La Dorotea.[9][3]
  • 1739 – Autoridades enters it.[3]
  • 1808 – first record from the Americas, in Uruguay.[11]
  • 1869 – the Academy adds “reducing to one kind” to the definition.[10]
