Forms

desmayo m (plural desmayos)[1]

Etymology

It is a deverbal noun from Spanish desmayar.[2][1][3] The verb was taken in the early 13th century from Old French esmaiier (“to disturb, frighten; to lose heart”), which comes from Vulgar Latin *exmagare (“to deprive of strength”), formed on the Germanic verb Proto-Germanic *magan (“to have strength, be able”).[3][4] The Vulgar Latin verb left native descendants in several Romance languages, such as Old Occitan esmagar and Italian smagare (“to confuse, perturb”), and probably Portuguese esmagar (“to crush”).[3] Corominas thinks it once covered the whole Peninsula until the French loan replaced it.[3] The same French verb was borrowed as Catalan desmaiar and Portuguese desmaiar, and it is the source of English dismay.[3]

Covarrubias in 1611 explained the noun from the month of May, as flowers and plants wither when May ends and the heat of June begins; the Diccionario de Autoridades repeated his explanation.[5][6]

Earliest recorded meaning

The CDH's earliest hit for the noun is in Berceo's Vida de San Millán de la Cogolla (c. 1230, in an 18th-century copy): Oídme, compañeros, si avedes desmayo “hear me, companions, if you are losing heart”.[7][8] The DCECH and the BDELC give a later first record, Don Juan Manuel's Conde Lucanor of about 1330–1335.[3][4] The medieval sense was “discouragement, loss of heart”, the sense of the verb, which in the Middle Ages always meant “to lose courage, grow faint”.[3]

Semantic evolution

The sense “fainting, loss of consciousness” grew out of the reflexive desmayarse, which Corominas finds only from the Golden Age on (Fray Luis de León, Mariana, Cervantes).[3] By 1726 the Diccionario de Autoridades defined the noun as a failing of the spirit and of the strength, with Saint Teresa's un desmayo, que ni dexa hablar ni menear “a faint that lets one neither speak nor move”.[6] In 1817 the Academy added “loss of the senses”.[9] The tree name followed: the weeping willow is desmayo in the Academy's dictionary from 1884, and Asturian desmayu and Catalan desmai have the same sense.[10][3] In Andalusia an almond tree with drooping branches is an almendro desmayo.[11] In the Canaries the word means “yawn”, and in Gran Canaria also “hunger”.[12][13]
