Pronunciation

  • /abeɾiˈɡwaɾ/, [a.β̞e.ɾiˈɣ̞waɾ][1]

Forms

averiguar (first-person singular present averiguo, first-person singular preterite averigüé, past participle averiguado)[1] Old Spanish also had verigar (in the Fuero Juzgo) and veriguar.[2][3][4]

Etymology

It is inherited from Old Spanish averiguar, inherited from Late Latin vērificō (“to present as true”), taken over in a semi-learned way, with the prefix ad-.[5][1][6] García de Diego sets up a Vulgar Latin *adverificāre, while Moliner and Gómez de Silva analyse the word as Spanish a- plus the Latin verb.[7][8][9] The fully learned form of the same Latin verb is verificar, recorded from 1578–1590.[5]

In Portugal it is Portuguese averiguar, first recorded in the 16th century, beside an older avergar.[10] Nascentes traces the Portuguese verb from the Latin one through a series of reduced intermediate forms, with a prothetic ⟨a⟩.[11] The form Asturian abriguar is found in Asturias and in Salamanca.[12]

The Late Latin verb is formed from vērus (“true”) and faciō (“to make, do”), with the second element as a causative suffix, and is first recorded in the 5th century.[1]

Earliest recorded meaning

Corominas, following Cuervo, dates the first record to the Fuero Juzgo of 1240.[5][1] Alonso quotes from it e se le averiguare su suciedad “and if his filthiness is proved against him”.[13] The CDH's earliest hit is the preterite auerigüé in Hermann the German's translation of the Psalter (c. 1240–1272).[14]

Semantic evolution

In 13th-century prose the verb meant both “to establish as true, verify” and “to discover”: in Alfonso X's Moamín (1250) a thing is mas aueriguado “more firmly established”, and an astronomical text of 1277 uses ueriguar for finding the true altitude of a star.[4][14] Covarrubias in 1611 defined it as “to get to the bottom of the truth” and traced it to the Latin adjective for “true”.[15] Autoridades had the same view.[15][16] In 1884 the Academy added the colloquial reflexive averiguarse con alguno “to come to terms with someone, keep someone in check”.[17]

In El Salvador the intransitive verb means “to argue heatedly, protest”, and in Nicaragua and Peru “to be nosy”.[18][6]
