Pronunciation

  • Classical: [ɫuː.kʊˈɫɛn.tʊs][1]
  • Ecclesiastical: [lu.kuˈlɛn.tus][1]

Forms

lūculentus (feminine lūculenta, neuter lūculentum, superlative lūculentissimus, adverb lūculenter); first/second-declension adjective[1]

Etymology

It is from Latin lūx (“light”) + -ulentus (“full of”),[2][1] formed like opulentus from ops, as the TLL notes.[3] De Vaan traces lūx to Proto-Italic *louk- (“light”) and Proto-Indo-European *leuk- (“light”).[4] The epitome of Festus already explained it as named from light.[3]

Earliest recorded meaning

It is found from Plautus on,[4][5] who has it of a bright, splendid vestibule in the Mostellaria and of a fine-looking woman in the Miles gloriosus (luculenta ac festiva femina).[6][2]

Semantic evolution

The literal sense “full of light, bright” is rare: Cicero writes of a stove with a good fire in it (camino luculento).[6] The usual sense is “excellent of its kind, splendid, fine”:[2][6] of riches and an inheritance in Plautus, of a fortune in Cicero,[2][6] of a legion, a style of speech, a writer or a witness worthy of trust.[6] Cicero also uses it ironically of a serious wound, “a fine wound, as the scar shows”.[2][6] Döderlein notes that it means what may be seen and need not shun the light, so that it never gives emphatic praise, unlike illūstris.[7] The comparative is found from Cicero on.[3] The adverbs are lūculentē and lūculenter.[6]

In Ecclesiastical Latin it means bright, splendid and excellent.[8] British medieval writers used it of fine appearance, of a keen mind, of eminent people, and of eloquent writing.[9]
