Forms
ayunar (first-person singular present ayuno, first-person singular preterite ayuné, past participle ayunado)[1] The Fuero Juzgo has ieiunar, geyunar, geiunar and iaiunar.[2] Old Spanish also wrote aiunar.[3]
Etymology
It is inherited from Vulgar Latin *iaiunare (“to fast”), the Vulgar Latin form of ieiunare.[4][5][6][1] Wiktionary explains the Vulgar Latin vowel from iaiūnus, the older form of the adjective, or by dissimilation.[1] The Latin verb is formed from Latin ieiūnus (“fasting, hungry”).[1][7] The noun ayuno is formed from the verb.[4][5]
The same verb is Portuguese jejuar, Catalan dejunar, Occitan jejunar, French jeûner, Italian digiunare and Romanian ajuna.[8][9] The REW leaves open whether the ⟨a⟩ of the Spanish and northern Italian forms goes back to the Plautine spelling ⟨jajunare⟩ or arose in Romance.[8]
De Vaan also takes the form with ⟨iai-⟩ as the older one; following Forssman he connects it with Proto-Indo-European *Hieh₂ǵ- (“to sacrifice”), the root of Ancient Greek ἅγιος (hágios, “holy”).[7] The OLD calls the origin unknown.[10]
Earliest recorded meaning
The earliest hit in the CDH is the Fazienda de Ultra Mar (c. 1200, in a 13th-century copy), in the story of Joseph's cup: bevie con el quando ayunava “he drank from it when he was fasting”.[11][3] Berceo's Vida de Santo Domingo de Silos (c. 1236) speaks of Christ going into the desert quando ayunar quiso “when he wished to fast”.[11][12] The DCECH, without these texts, dates it to the Fuero Juzgo of 1241.[4][5]
Semantic evolution
Alfonso X's prose already has the three senses of today: to go without food, to keep a fast of the Church, and figuratively to be deprived of something.[13] Autoridades in 1726 added ayunar a pan y agua, to live on bread and water, and the Academy in 1770 ayunar al traspaso, a fast from Maundy Thursday to Holy Saturday.[14][15] The Academy's dictionaries recorded the proverb harto ayuna quien mal come “he who eats badly fasts enough” from 1817.[16] The phrase ayunarle a alguien, to fear or respect someone, is in the Quijote and in the Academy's dictionary from 1884; the DLE now marks it obsolete.[17][18][6] From the verb come ayuno and desayunarse, “to break one's fast”, first recorded in 1490.[5]
