Pronunciation

  • Ecclesiastical: [ˈruː.bor][1]

Forms

rubor m (genitive rubōris); third declension[1]

Etymology

It is from Latin rubeō + -or, from the verb “to be red”.[2][3] De Vaan lists it among the derivatives of ruber (“red”), which goes back to Proto-Italic *ruþro- (“red”) and Proto-Indo-European *h₁rudʰ-ró- (“red”), cognate with Umbrian rufru (“red”), Sanskrit रुधिर (rudhirá, “red, bloody”) and Ancient Greek ἐρυθρός (eruthrós, “red”).[4]

Earliest recorded meaning

De Vaan dates it from Accius,[4] who has eyes gleaming with a flaming redness.[2]

Semantic evolution

It is redness of every shade, as Cicero's red mixed with white, and of the complexion, sometimes as a sign of health, as Ovid's fair skin suffused with rosy red.[2][3] It is also the redness of inflammation or fever, as in Ovid's plague, and of a face red with anger in Gellius.[2] Specifically it is a blush from shame or modesty, as Cicero's “so that a blush follows shame”, then the feeling of shame itself, as Livy's consul who came through the crowd of women not without some shame, and the capacity to blush, modesty.[2][1] By metonymy it is what causes shame, disgrace, as Cicero's censor whose verdict brings nothing but disgrace.[2][1]

Church Latin glosses it “shame”.[5]
