Pronunciation

  • /oˈbɾeɾo/, [oˈβ̞ɾe.ɾo][1]

Forms

obrero (feminine obrera, masculine plural obreros, feminine plural obreras)[1] Old Spanish texts also write obreyro and hobrero.[2]

Etymology

It is inherited from Latin operārius (“labourer, workman”).[3][4][5][1] Wiktionary notes that it can also be analysed within Spanish as obra with the suffix -ero.[1] Its learned doublet is operario, borrowed at the start of the 17th century.[3][5]

The same Latin word is Portuguese obreiro, Galician obreiro, Asturian obreru, Catalan obrer, Old Occitan obrier, French ouvrier and Italian operaio.[6][5][7]

The Latin word is an adjective, “working for hire”, formed from opera (“effort, work”), used as a noun for a labourer.[8][1] This noun in turn belongs to opus (“work”), from Proto-Indo-European *h₃ep-os (“work”).[9]

Earliest recorded meaning

The BDELC and DEMel date the word to 1056, with the plural obreros in a charter of the Cartulario de Santillana.[3][2] In Alfonso X's General estoria (1272–1275) it means a man who works for pay: omnes obreros que labrassen por sus dineros “working men who would labour for their money”.[10]

Semantic evolution

Old Spanish used it for anyone who works, as in the Alfonsine history of Spain, where the caliph works with the master builders and the obreros on the bridge of Córdoba, and Berceo also used it for a devout servant of the Virgin.[10][11] The Diccionario de Autoridades defined it as a day labourer in building and in the fields, and gave the figurative sense of one who works for the salvation of souls, as well as the official who looked after the building works of a church, a dignity in some cathedrals.[12] Medieval Latin operārius had the same sense of a church warden.[13]

The Academy's dictionaries of 1884 and 1899 derived it from obra; the 1899 edition defined it as a person who works at a trade or with their hands.[14][15] In the 19th and 20th centuries it became the word for the industrial worker, with the derivatives obrerismo and obrerista.[3][4] In Honduras an obrero is a stud donkey.[16]
