Pronunciation

  • IPA (Classical): [ˈɫuː.ke.oː][1]
  • IPA (Ecclesiastical): [ˈluː.t͡ʃe.o][1]

Forms

lūceō (present infinitive lūcēre, perfect active lūxī); second conjugation, no supine stem[1]

Etymology

It is inherited from Proto-Italic *l(o)ukē- (“to be light”), inherited from Proto-Indo-European *luk-éh₁- (“to be light”), from the root Proto-Indo-European *lewk- (“to shine”) of lūx “light”.[2][1][3] De Vaan notes that the stative has an unexpected full grade, perhaps from the causative *lowk-éye- or from the root noun, and that the transitive sense “to light” found in Plautus may be old.[2]

Earliest recorded meaning

The OLD's first citation is Ennius, who speaks of bright lights shining.[3] Köbler dates Ennius 204–169 BC.[4]

Semantic evolution

It meant to emit light, shine, of heavenly bodies and fire, as Cicero's star shining with borrowed light, and impersonally lūcet “it is light, day dawns”.[3][5] Of polished surfaces it meant to shine with reflected light, glitter, and figuratively to be clear, evident, as in Cicero.[3] Döderlein says lūcēre is a steady brightness, while fulgeō is a glaring one.[6]

It survives in Italian lucere, French luire and Spanish lucir.[1] English lucid comes from its adjective lūcidus, recorded in the 1590s.[7]
