Pronunciation

  • Portugal: /ˈka.ɾu/[1]

Forms

caro (feminine cara, masculine plural caros, feminine plural caras, comparable, comparative mais caro, superlative o mais caro or caríssimo)[1]

Etymology

It is inherited from Latin cārus (“dear, precious, beloved”), already Old Galician-Portuguese caro in the 13th-century texts.[2][3][1] The Latin word meant both “costly” and “dear, loved”, and the Portuguese word has kept both senses.[2]

The same Latin word is Galician caro, Spanish caro, Catalan car, Occitan car, French cher and Italian caro.[4][1] The Spanish word is recorded from the poem of the Cid.[5][6]

The Latin word goes back to *kāros and *kéh₂ros (“desired, desirable”), from a root meaning “to wish, to love”.[7][1] De Vaan compares Gaulish personal names, the Latvian kārs (“lustful”) and the Old Irish carae (“friend”).[7]

Earliest recorded meaning

The Cantigas de Santa Maria of the 13th century use the word in both its senses: the Mother of God is someone devemos tẽer mui cara “we must hold very dear”, and one cantiga tells of a man who gave all he had to the poor en ũu ano caro “in a year of dearth”.[8] The troubadour Pero da Ponte plays on the contrast between caro “dear, costly” and rafece “cheap”.[8]

Semantic evolution

The Crónica Troiana has lles custou moy caro a sua morte “their death cost them very dear”, and the medieval chronicles speak of bread sold caro “at a high price”.[8] Bluteau describes the word as what costs more than it is worth, and adds the sense of a victory bought with blood and lives.[9] Morais (1789) records both the price sense and “beloved”, with the adverbial use in custar caro.[10] Houaiss and Aurélio put the price senses first and “dear, beloved” after them.[2][11]

Timeline

  • 13th century – first records, in both senses, in the Cantigas de Santa Maria.[2][8]
  • c. 1430 – first occurrence in the CTA corpus, in the Horto do Esposo.[12]
  • 1562 – first record of the derivative careiro.[3]
  • 1712–1728 – Bluteau defines the word by its price sense and records victoria cara.[9]
  • 1789 – Morais gives the price sense first and “beloved” second.[10]

Usage notes

Aurélio advises against the phrase preço caro, since the price itself is high, not dear.[11]

Houaiss and Aurélio also record a Brazilian ethnonym caro, a people of the Ramarama family of Rondônia, and Houaiss a botanical noun caro for the plants of the genus Carum, from Greek; both are separate words.[2][11]
