Forms

obra f (plural obras)[1] Medieval texts also write hobras, oobra and obrras.[2]

Etymology

It is inherited from Latin opera (“effort, work”), written Old Galician-Portuguese obra in the oldest texts.[2][3][1] It is the popular doublet of the learned ópera.[2][1]

The same Latin word is Galician obra, Spanish obra and Spanish huebra (“a day's work in the field”), Catalan obra, French œuvre and Italian opera.[4][1][5]

The Latin feminine grew out of the neuter opus (“work”), whose plural was reinterpreted as a singular;[1][6][7] Latin speakers distinguished ⟨opera⟩, effort freely given, from ⟨opus⟩, the work itself.[1][6][7] De Vaan reconstructs Proto-Indo-European *h₃ep-os (“work”).[7]

Earliest recorded meaning

Houaiss's earliest date, 1188, comes from Machado's records.[2] In the Cantigas de Santa Maria the word means a deed (fez obras noit' e dia “did deeds night and day”), work on the Sabbath, and a painting (hũa obra mui fremosa / pintava da Santa Virgen).[8][3]

Semantic evolution

In the medieval chronicles obra is also building work: the Crónica Troiana speaks of the workers and masters of the building of a tomb, and the Crónica Geral of the fine work of the Torre do Ouro.[8] Houaiss dates the sense “building under construction” to the 13th century and the sense “printed work, book” to the 15th.[2] Religious language gave obras de misericórdia, and the total output of an artist or writer is a obra.[2][9] Viterbo notes the old obra de “about, roughly”, as in obra de doze legoas “about twelve leagues”.[10] Morais in 1813 records the naval obras mortas and obras vivas, the upper and lower parts of a ship's hull.[11] Popular senses are a trick or scheme and a bowel movement.[12][2][13] In the north-east of Brazil a stanza of a sung contest is an obra.[14]
