Morphology

fluorescent = fluoresce (opaque) = fluoresce + nt

The verb 'fluoresce' is itself rare and technical, so the formation of 'fluorescent' is not transparent to most learners.

Etymology

Fluorescent comes from the mineral fluorite, which often seems to glow when light hits it, and that mineral's name comes from a Latin root meaning 'to flow', like in fluid. So fluorescent describes things that 'glow' and give off light when another light shines on them.
