Etymologically

candeo

Etymology and origin of the Latin word candeo

Pronunciation

  • IPA (Classical): [ˈkan.de.oː][1]
  • IPA (Ecclesiastical): [ˈkan.de.o][1]

Forms

candeō (present infinitive candēre, perfect active canduī); second conjugation, no passive, no supine stem[1]

Etymology

It is inherited from Proto-Italic *kand-ē- (“to shine”), a stative verb from a root Proto-Indo-European *(s)kend- (“to shine, glow”).[2][1] If the root was *knd-, Latin a is unexpected; de Vaan explains it by a rule that inserts a to break up a cluster of four consonants, in formations such as *knd-ro- or *knd-no-.[2]

Cognate with Welsh cann (“brilliant”), Sanskrit चन्द्र (candrá-, “shining”) and Albanian hënë (“moon”).[2][1] The OLD and Georges also compare Ancient Greek κάνδαρος (kándaros, “charcoal”).[3][4]

Earliest recorded meaning

It is attested from Ennius onwards,[2] who describes land and sea that “gleam with trembling light”.[3]

Semantic evolution

The verb meant to shine and especially to gleam white, as ivory or marble does, and less often to glisten in other colours.[3][5] From the glow of hot metal it also meant to be or become hot, as of the air in Ovid's iron age.[3][6] It was mostly poetic, and its present participle candens was used as an adjective “dazzling, white, glowing”.[5][4]

Its derivatives were more productive than the verb itself: candidus, candor, candela, and the compounds accendo and incendo “to set on fire”.[2][7]

  • 204–169 BC – Ennius uses it of shining light.[3][8]
  • 81/79–52/50 BC – Catullus writes that ivory gleams on the thrones.[3][8]
  • 65–8 BC – Horace uses it of a scarlet cloth glistening on couches.[3][8]
