Morphology

luminesce = luminous (semi-transparent) = lumin + esce

The transformation from 'luminous' to 'luminesce' involves a shift from an adjective to a verb, which may not be immediately clear to all learners.

Etymology

Luminesce comes from the Latin root lumen meaning 'light' and the ending -esce meaning 'to become'. So, to luminesce is to 'become light' and means to give off light without heat, like glow-in-the-dark paint or deep-sea animals.
