Forms
duro (feminine dura, masculine plural duros, feminine plural duras, superlative durísimo)[1]
Etymology
It is inherited from Latin dūrus (“hard”).[2][3][4][1] Old Spanish had the same form, duro.[1][5]
The same word is Portuguese duro, Galician duro, Catalan dur, Occitan dur, French dur, Italian duro, Sardinian duru and Romanian dur.[6][7][1] The adverbs adur, de dur and a duro “hardly, with difficulty”, frequent in Berceo, are explained by Corominas as a cross of the last two phrases with a preliterary adverb *dur, from dūrē (“harshly”).[2] a duras penas arose from a duras combined with apenas.[2]
The origin of the Latin word is disputed.[8] De Vaan and Wiktionary derive it from *duh₂-ró- (“long”), which is also the source of Ancient Greek δηρός (dērós, “long”) and Sanskrit दूर (dūrá, “far, long”).[9][1] Wiktionary notes that this meets semantic problems, while De Vaan holds that the verb dūrō developed from “to be hard” to “to endure, last”.[1][9] The OLD and Gómez de Silva prefer an older form *drūros, connected with Lithuanian drūtas (“strong”) and Irish dron (“firm”), from the root of words for “tree” and “wood”, but the dissimilation it requires is not otherwise attested.[10][11][12]
The noun for the coin is a clipping of peso duro, the silver peso worth twenty reales.[13][14]
Earliest recorded meaning
Corominas dates the word to a charter of 1205 in Oelschläger's list, and to Berceo.[2][3] In Berceo it also means “bad, evil” and, of a rope, “strong”; the Libro de Alexandre has en duro punto “at an evil hour”.[2] Alfonso X's prose uses it of hard things such as stones and metals, of bodies hardened to toil, of harsh terms and of cruel anger.[15]
Semantic evolution
The figurative senses “hard to bear”, “cruel” and “stubborn” were present from the start; the Libro de buen amor already speaks of pesos duros.[5][2] Autoridades (1732) defines duro as what is solid and breaks with difficulty, then by likeness stale bread and hard-boiled eggs, and figuratively “unbearable” and “cruel”.[16]
As a noun duro named the silver peso of twenty reales in Domínguez (1846) and in the Academy's 1869 edition.[17][14] The DLE now defines it, for Spain, as the five-peseta coin.[4] The 1869 edition also records the adverb, ¡dale duro! “hit him hard!”.[14]
In the Americas duro means “drunk” in Mexico and Uruguay and “stingy” in many countries, duro y parejo means “steadily and hard”, and as an adverb it means “loudly” in Central America and the Caribbean.[18][19] In Panama a duro is a frozen soft drink.[4][19]
