Pronunciation

  • Classical: [rʊˈbeːs.koː][1]
  • Ecclesiastical: [ruˈbɛs.ko][1]

Forms

rubēscō (present infinitive rubēscere, perfect active rubuī); third conjugation, no passive, no supine stem[1]

Etymology

It is from Latin rubeō (“to be red”) + -scō,[2][1][3] an inchoative verb.[3] De Vaan lists rubeō with ruber (“red”), which goes back to Proto-Italic *ruþro- (“red”) and Proto-Indo-European *h₁rudʰ-ró- (“red”).[4]

Earliest recorded meaning

It is first found in Virgil:[3] in the Aeneid the dawn is reddening, the sea reddens with the sun's rays, and the fields of Neptune redden with fresh slaughter.[3][5]

Semantic evolution

Lewis and Short call it poetic and found in post-Augustan prose.[3] Ovid uses it of the morning and of rocks reddened with blood, and Pliny the Elder of roses.[3][6] The OLD notes the present participle used as an adjective, “reddish”.[2]

Seneca uses it of blushing: nothing was gentler than Pompey's face, which always blushed before company.[2][3][5] Jerome writes of cheeks that redden charmingly.[5]

Timeline

  • 70–19 BC – Virgil uses it of the dawn and the sea.[3][5]
  • 43 BC–18 AD – Ovid uses it of the morning and of blood-stained rocks.[3]
  • 4 BC–65 AD – Seneca uses it of blushing.[2][7]
  • c. 383–419/420 AD – Jerome uses it of reddening cheeks.[5][7]

Meanings

Verb

  1. To become red, redden; present participle, reddish.[2][3]

Usage notes

In Ovid's Metamorphoses 7.78, where older editions read rubuere, the text now has erubuere from ērubēscō.[5]
