Morphology

phosphorescent = phosphor (opaque) = phosphor + escent

The word is historically built from 'phosphor' plus the Latinate suffix '-escent', but the scientific meaning is not obvious to an average B1 learner.

Etymology

The word phosphorescent comes from Greek phosphoros meaning 'light-bringer' and the ending -escent meaning 'becoming'. So something phosphorescent slowly 'becomes light' and glows in the dark without giving off heat.
