luceo

The transitive meaning of the term appears only in Plautus and may derive from Proto-Italic *loukeō, from Proto-Indo-European *lowkéyeti, whence also Sanskrit rocáyati and Proto-Slavic *lučiti. However, the intransitive meaning of the term may derive from Proto-Italic *loukēō, which derives from the older stative *luk-éh₁-ye-ti.
