Pronunciation

  • /auˈnaɾ/, [au̯ˈnaɾ], [a.uˈnaɾ][1]

Forms

aunar (first-person singular present aúno, first-person singular preterite auné, past participle aunado)[1] Cantabrian has ajunar, with the ⟨j⟩ of juntar.[2]

Etymology

It is inherited from Late Latin adūnō (“to make one, unite”).[3][4][5][1] The Latin verb is formed from ad- (“to”) and ūnus (“one”).[1][6] Lewis and Short find it mostly in Justin and the Church Fathers.[7] The same verb is Portuguese aunar, Catalan aunar, Old French auner, Old Occitan azunar, Italian adunare and Romanian aduna, and Judeo-Spanish has Ladino ardunar.[8][2]

The Latinising form adunar appears in Fray Luis de León and others.[3] Berceo's aungar and ungar are not from a Vulgar Latin *adūnicō, in Corominas's view, but forms built on the present indicative and subjunctive of uncir, which continues iungō (“to yoke, join”).[3]

The numeral continues *oinos, from *Hoi-no- (“one”).[9][1]

Earliest recorded meaning

Corominas dates it to 1555, in the Viaje de Turquía, but the verb is older.[3][4] The DEMel finds the participle aunado in 13th-century documents from Sahagún.[10] The first part of Alfonso X's General Estoria (c. 1275) has por estas razones aunadas, “for these reasons taken together”, and the second part acordaron de yr todos aunados a ell, “they agreed to go at him all together”.[11][10]

Semantic evolution

Autoridades (1726) defines it as making people who were divided agree on a resolution or party, and notes that it is used more often as a reflexive “to unite, to league together”: se aunaban y conjuraban unas familias con otras.[12] The Academy's 1817 edition adds a second sense, to mix two or more things into a single body.[13] Cuervo collects both the transitive and the reflexive use in Quevedo, Coloma and Luis de la Puente.[14] Today it is used mostly with abstract objects: aunar esfuerzos, aunar criterios.[15][16] Judeo-Spanish aunarse kon means to side with someone.[17]

Timeline

  • c. 1275 – Alfonso X's General Estoria uses aunadas and aunados.[11]
  • 1555 – the Viaje de Turquía, Corominas's first record.[3][4]
  • 1576 – first record from the Americas, in Mexico.[18]
  • 1726 – Autoridades records it, mostly as a reflexive.[12]
  • 1817 – the Academy's dictionary adds the sense “to mix into one body”.[13]
  • 1884 – the Academy's dictionary refers it to adunar.[19]

Meanings

Verb

  1. To unite or ally people for a purpose; mostly reflexive: Los gremios se aunaron para defender sus derechos.[5][1]
  2. To unify (unificar), make into one.[5]
  3. To bring together or harmonize several things: aunar esfuerzos.[5][15][16]

Word family

  • aunamiento

Usage notes

The stressed ⟨u⟩ of the present takes a written accent, as in aúno, aúnan, like aullar.[15][1]
