Pronunciation
Forms
rubicundus (feminine rubicunda, neuter rubicundum, comparative rubicundior); first/second-declension adjective[1] Comparative rubicundior.[2]
Etymology
It is from Latin rubeō (“to be red”) + -cundus.[2][1] De Vaan traces ⟨ruber⟩ to Proto-Italic *ruþro- (“red”), Proto-Indo-European *h₁rudʰ-ró- (“red”), cognate with Umbrian ⟨rufru⟩ and Ancient Greek ἐρυθρός (eruthrós, “red”).[3]
Earliest recorded meaning
Lewis & Short and Gaffiot cite Plautus' Pseudolus, ōre rubicundō “with a ruddy face”.[4][5] Köbler dates Plautus c. 250–184 BC.[6]
Semantic evolution
It meant red, ruddy, flushed, of the face and complexion, as in Plautus and Terence, and of crops red-gold, as in Virgil's rubicunda Cerēs “the ripened harvest”.[2][4][5]
British Medieval Latin used it for red, rosy, of the complexion and of the Red Sea, and it passed into a surname.[7] English rubicund (early 15th century) is from it.[8]
