Pronunciation

  • Classical: [ˈrʊ.be.ʊs][1]
  • Ecclesiastical: [ˈruː.be.us][1]

Forms

rubeus (feminine rubea, neuter rubeum); first/second-declension adjective[1] Also rōbeus, rōbius and rūbius; the OLD gives the word as rūbeus, a variant of rōbeus.[2][3]

Etymology

The adjective “red” is from Latin rubeō (“to be red”).[4][1] Georges and Gaffiot connect it with ruber (“red”),[3][5] while the OLD treats it as a variant of rōbeus and compares rōbus (“a kind of red”).[2] De Vaan explains rōbus as a dialectal form, with ⟨ō⟩ for ⟨ū⟩, of the adjective found in rūfus, from Proto-Italic *rouþo- (“red”) and Proto-Indo-European *h₁re/oudʰ-o- (“red”).[6]

It survives in Old French roge, French rouge, Catalan roig and Italian robbio.[1] French rouge is the source of English rouge.[7]

Earliest recorded meaning

Varro uses it of the colour of livestock, preferring black first and red next.[2][8][9]

Semantic evolution

In Classical Latin it is mostly a word for the red or reddish coat of animals: cattle and hens in Columella, a red calf in an inscription, and, in a decree quoted by Gellius, red sacrificial victims.[2] Palladius uses it of an ass.[8][5] Wiktionary calls it chiefly Late Latin.[1]

In British Medieval Latin it is the common word for red: of blood, wine, cloth, wax, soil and stone, of reddish-brown horses and oxen, of smoked (red) herring, of red bile, and in heraldry for gules.[10]

Timeline

  • 116–27 BC – Varro uses it of the colour of livestock.[2][9]
  • 1st century AD – Columella prefers hens of a red colour for breeding.[2][9]
  • end of 4th/beginning of 5th century AD – Palladius uses it of an ass.[8][5][9]
  • Medieval Latin – It is the ordinary word for red in British records, including heraldry.[10]
  • 1753 – French rouge is borrowed into English as rouge.[7]

Forms

Etymology

The adjective “of bramble” is from Latin rubus (“bramble”) + -eus.[2][1][3]

Earliest recorded meaning

Virgil has rubeā texātur fiscina virgā, “let a basket be woven of bramble twigs”.[2][11][9]

Semantic evolution

It is a rare word, known from Virgil's line in the Georgics.[2][3][11] Gaffiot reads the phrase virga rubea as the red-stemmed dogwood, giving it under the colour adjective.[5]

  • 70–19 BC – Virgil speaks of a basket woven from bramble twigs.[2][11][9]

Meanings

Adjective

  1. Of a bramble, made from bramble: virga rubea “a bramble twig”.[2][8][3]

Usage notes

In Virgil's line some editors, among them Ribbeck, read Rubea “of Rubi”, a town in Apulia, instead of rubea.[3]
