Morphology

fluorescein = fluoresce (semi-transparent) = fluoresce + in

Formally built from the verb 'fluoresce' plus the chemical noun suffix '-in', indicating a substance that fluoresces, but the technical chemical suffix and specialist nature make it only partially transparent to general learners.

Etymology

Fluorescein comes from the same root as fluorescent: fluor- which means 'to glow' or 'give off light'. So fluorescein is the name of a dye that 'glows' brightly under ultraviolet light.
