Pronunciation

  • /ˈroxo/, [ˈro.xo][1]

Forms

rojo (feminine roja, masculine plural rojos, feminine plural rojas)[1] Old Spanish and Golden Age texts spell the word roxo, the spelling under which the Diccionario de Autoridades still enters it.[2][3] The prose of Alfonso X has roxo and the plural rosios.[4] Leonese of Babia has roixo and roxio;[5] Asturian has roxu.[6][5]

Etymology

It is inherited from Old Spanish roxo, inherited from Latin russeus (“deep red”).[2][7][1] The DLE gives instead the simpler adjective russus (“red”), from which the Latin word is derived.[8][9] García de Diego also files the word under the simpler adjective and notes that a Latin /ss/ can give Spanish ⟨j⟩ without a following /e/, as in vejiga.[6] Wiktionary compares the same development of /ss/ in bajar and cejar.[1]

Corominas notes that the derived adjective was used by the authors of the Silver Age and by Petronius, and that it survives only in Portuguese, Spanish and the dialects of central and southern Italy.[2] From it come Portuguese roxo and Galician roxo; from the simpler adjective come Italian rosso, French roux and Catalan ros.[2][10][11] Nocentini derives Romanian roșu from the derived adjective too, but Corominas holds that the Romanian word continues roseus (“rose-coloured”).[10][2] French rouge and Catalan roig are of another Latin adjective, rubeus, and have no direct connection with the Spanish word.[7][2]

The simpler adjective goes back to Proto-Italic *russos and ultimately to Proto-Indo-European *h₁rewdʰ- (“red”).[1] Nocentini reconstructs it as *rudh-tos, from the same root as the French and Catalan words.[10]

Earliest recorded meaning

The prose of Alfonso X has the word for a bull rising in the fifth degree of a sign, enel quinto grado sube un toro roxo “in the fifth degree a red bull rises” (siglum PIC, 1256?), in the sense of a vivid golden or reddish colour.[4] Another Alfonsine text (siglum MOA) tells the reader to heat bricks fasta que sean bien rosios “until they are quite red”.[4] DEMel lists the forms ruyo and Roio from charters of Oña (1144) and Huesca (1148).[12] Corominas notes that the Portuguese word appears as a man's name or nickname in documents from about 1060, and that the surname Rojo is very common in Spain and Portugal.[2]

For Corominas the word is foreign to almost all medieval literature: the Cid, Berceo, the Libro de Alexandre, Juan Ruiz and the Celestina say bermejo.[2] His first records are a 15th-century Jewish Bible translation (Genesis 30:40) and G. de Segovia in 1475.[2]

Semantic evolution

In the Middle Ages the usual word for the colour of blood was bermejo, while colorado and encarnado appear later, perhaps no earlier than rojo.[2] Corominas concludes that the medieval word named a less common, lighter shade, the reddish colour of hair still fixed in pelirrojo and the classical barbirrojo “red-bearded”: Nebrija translated it by Latin rutilus “reddish, golden”, and Alcalá by an Arabic word for “reddish” or “blond”.[2][7] A. Castro had argued that it always meant the colour of blood, and C. de las Casas in 1570 already contrasts roxo “red” with ruvio “blond”.[2] Corominas does not rule out that French rouge helped the shift to the modern sense in the 18th century.[2] Portuguese roxo went another way and now means “purple”.[2][13]

The Diccionario de Autoridades defined roxo as a very bright red like that of blood, and also as golden like the sun.[3] In 1884 the Academy called it the first colour of the solar spectrum.[14] The political sense “left-wing, communist” is now in the DLE, with the Civil War sense “Republican”, the name the Nationalists gave their opponents.[8][15] In Colombia and Honduras rojo means a supporter of the Liberal Party, and in Honduras and Nicaragua a failing grade.[16]
