Morphology
luminol = lumin + ol
Although formed from the combining form 'lumin-' (light) + the chemical suffix '-ol', 'lumin' is not a standalone English word and the term is a specialized chemical name, so its meaning is not transparently derived for an average B1 learner.
Etymology
The word luminol comes from the Latin root lumin- meaning 'light' and the chemical ending -ol, and it shares the same root as luminous. Because the chemical makes a blue light when it finds blood, its name is a simple way to remember its glowing effect.
