Forms

obreiro m (plural obreiros, feminine obreira, feminine plural obreiras)[1]

Etymology

It is inherited from Latin operārius (“labourer; of work”), with the same form in the oldest texts.[2][3][1] It is the popular counterpart of the learned operário, taken from the same Latin word.[2][1] Nascentes allows that it may instead have been formed in Portuguese, from Portuguese obra + -eiro, an analysis Wiktionary also notes.[4][1]

The same Latin word is Galician obreiro, Spanish obrero, Catalan obrer, French ouvrier and Italian operaio.[5][1]

The Latin adjective is formed from opera (“work, effort”) with the suffix -ārius.[6][1] De Vaan derives the noun from opus (“work”), from Proto-Indo-European *h₃ep-os (“work”).[7]

Earliest recorded meaning

The Cantigas de Santa Maria tell of triinta obreiros “thirty workmen” digging, and use the word figuratively when they say that companions deven seer obreiros, / loand' a virgen santa “should be workers, praising the holy Virgin”.[8] Another cantiga has a man who comprou fouces, terra e obreiros “bought sickles, land and labourers”.[9]

Semantic evolution

Bluteau (1712–1728) defines the obreiro as a craftsman who works for his living and records obreiro evangélico “labourer of the Gospel”, a missionary.[10] Morais (1813) has “a worker on building works”, quoting the Ordenações Afonsinas.[11] Vieira (1871–1874) adds o grande obreiro for God and the figurative sense of anyone who brings about a result.[12]

The DLP now marks the sense “manual worker” as disused, the usual word being operário, while the figurative sense, someone who works for an idea or a cause, remains current.[13][14] As an adjective it names the worker caste of social insects such as bees and ants.[2][15] In Galician obreiro is also the master of works and the cleric in charge of building in a church, a sense Medieval Latin operarius already had.[16][17]

Timeline

  • 1258 – Machado's first date, for the form Obreira, as cited in Lorenzo's chronology.[8]
  • 13th century, second half – obreiros in the Cantigas de Santa Maria.[8][3]
