Forms

operación f (plural operaciones)[1]

Etymology

It is borrowed from Latin operātiō (“work, working; operation”), a learned word.[2][3][1][4] The Latin noun is formed from operor (“to be at work”) with the suffix -tiō.[5][1] The verb is derived from opus (“work”),[2][6] which de Vaan traces to Proto-Indo-European *h₃ep-os (“work”).[7]

From the same Latin verb Spanish inherited obrar “to work, act”, beside obra from the plural noun opera; the learned verb operar is recorded only from 1737, long after the noun.[2] The same learned borrowing is Portuguese operação, Galician operación, Asturian operación, Catalan operació and Italian operazione.[8][9][10][1]

Earliest recorded meaning

The first record is in Alfonso X's Libro del Alcora (1277, in a copy of the same period), where the reader finds the same result “doing this operation” at any degree of the zodiac: faziendo esta operacion en qual grado quier de los grados del zodiago.[11][12] The sense is the carrying out of a working or procedure.[12] The BDELC and Segura Munguía, without this text, date the word 1433.[2][4]

Semantic evolution

In 14th-century texts the word is used of the “operation” or activity ascribed to Christ in the debates over his wills, una voluntad & una operaçion, and in the plural of the workings of magical arts.[11] In 16th-century texts from the Americas it means the effect of a remedy or a plant (tienen las mismas operaciones, Mexico 1576), and the Diccionario de Autoridades still gives this sense, saying that remedies have had a good operation or none.[13][14] Nebrija's Latin–Spanish dictionary (1492) glosses operatio as aquel obrar “that working”.[15]

The surgical sense appears in the 19th-century dictionaries, which define it as the hand, alone or with an instrument, applied to the living body to cure a disease or correct a defect; the Academy added operación cesárea in 1899.[16][17] The DLE now adds the commercial sense, a deal in securities or goods, and the mathematical one, a set of rules for obtaining results from data.[3] Moliner and the Wikcionario also record military and police operations.[18][19]

In Puerto Rico the word has taken from English the sense “management, running” of an activity.[20] In Chile it was a euphemism for the castration of animals.[21] Spanish America has many set phrases, such as Mexican operación cajón, for an employee who stops work with tasks unfinished when the working day ends, and operación rastrillo in Argentina and Uruguay, a police or military round-up.[22]
