Forms

obra f (plural obras)[1] The older Old Spanish form is huebra;[2] DEMel also records hobra and vobra.[3][2]

Etymology

It is inherited from Old Spanish obra, inherited from Latin opera (“work, effort”); the older form huebra gave way to it under the influence of the verb obrar.[3][1][4][5] Modern Spanish keeps it as huebra, a day's work in the fields and the land that can be ploughed in a day, with the dialect forms huerba and güebra.[3][6] The same Latin word had these meanings in the Middle Ages: a day's compulsory field labour, and a measure of land ploughed in one day.[7] ópera, borrowed from Italian and first recorded in 1737, is a doublet.[3][1]

The same word is Portuguese obra, Catalan obra, Occitan òbra and Italian opera.[8][6][9] Wiktionary explains the Latin noun as the plural of opus (“work”) taken as a feminine singular.[1] De Vaan lists it among the derivatives of that noun, which he traces to Proto-Italic *opes- (“work”) and Proto-Indo-European *h₃ep-os (“work”).[10]

Earliest recorded meaning

Corominas dates the old form huebra to about 1140, especially in the sense “the work done in one day”, and obra to about 1250.[3] In the CDH the earliest text is the Fuero de Madrid (dated between 1141 and 1235, in a copy of the first half of the 13th century), which speaks of a payment „per a la obra del adarue” “for the building of the wall-walk”.[11]

Semantic evolution

By the time of Alfonso X the word meant a thing made by someone, a work of the mind (“the work of astrology”), a building under construction, and the effect or power of something, such as a precious stone.[12] Berceo uses it for work and practice, and also for fine handiwork: a chasuble „obra era angelica, non de omne texida”.[13] The Diccionario de Autoridades recorded the writings of an author and a building being put up or repaired.[14] An obra de with a number meant “about”: obra de diez leguas “about ten leagues” is recorded in Santa Marta in 1526.[15][16] The Academy's 1843 edition gives the proverb obra comenzada no te la vea suegra ni cuñada, advice to hide a plan from those who might stop it.[17]

Baralt rejected poner en obra in the French sense “to make use of” as a gallicism.[18] In Cuba obra also meant a trick or tall story.[19] Building terms vary across the Americas: obra negra and obra gris are a building that still lacks its finishes, and obra fina the finishing work.[20]
