fulgēns (genitive fulgentis, comparative fulgentior, superlative fulgentissimus); third-declension one-termination adjective[1][2]

Etymology

It is the present participle of fulgeō (“to flash, shine”), used as an adjective.[1][2] The verb is older ⟨fulgere⟩, going back to Proto-Italic *folgō and to a root Proto-Indo-European *bʰlg- (“to shine”); the participle is the oldest attested form of the verb.[3] Cognate with Ancient Greek φλέγω (phlégō, “to burn”) and Ancient Greek φλόξ (phlóx, “flame”).[3]

Earliest recorded meaning

De Vaan dates it from Ennius,[3] whose Annals have the sky fitted with gleaming stars.[1]
