Pronunciation

  • Brazil: /ˈɔ.ʎu/, /ˈɔ.lju/[1]
  • Portugal: /ˈɔ.lju/[1]

Forms

óleo m (plural óleos)[1] Old Galician-Portuguese wrote oyo in the 13th century, oleo, olio and oolio in the 14th, and holio and ollyo in the 15th.[2][3] Feijó in 1734 still had to insist on óleo, not olio.[4]

Etymology

It is borrowed from Latin oleum (“olive oil”).[2][3][1] The medieval forms include Old Galician-Portuguese oyo, Old Galician-Portuguese olio and Old Galician-Portuguese oolio.[2][3] Meyer-Lübke, as Nascentes reports, held Spanish óleo and French huile to be learned forms like the Portuguese, because the word kept three syllables: its /e/ did not become a glide that would have palatalised the /l/, as in palha.[5] The popular Portuguese word for olive oil is azeite.[5][6]

The Latin noun comes from an older olīvum.[7] It is from Ancient Greek ἔλαιον (élaion, “olive oil”), from ἐλαία (elaía, “olive; olive tree”).[2][1]

Earliest recorded meaning

A miracle of the Cantigas de Santa Maria tells how the Virgin of Ribela will not let any oil burn before her altar senon d'olivas “unless it is of olives”, clear and well refined: non quer que arza outr'oyo ant'o seu altar.[8] The Miragres de Santiago have olio for oil to anoint oneself with, and for oil of balsam, myrtle or olive burnt in lamps.[9]

Semantic evolution

Nascentes notes that the word first meant olive oil, that after the Arab rule azeite took its place in that sense, and that it was later widened to other oils, including mineral ones.[6] Morais in 1813 defines it as a rich, unctuous liquid drawn from plants by fire or pressing, and records the Santos Óleos of the sacraments and the figurative óleo da Graça.[10] Vieira lists oil of almonds, of linseed and of cod liver.[11] The noun oleado “oilcloth” is recorded in 1813.[3]

Brazilian Portuguese uses it for petroleum, and informally for sugar-cane spirit and for money; it is also the name of the copaíba trees, whose bark holds a medicinal oil.[2][12][13] In art it means an oil painting.[2][1]
