Morphology
chemiluminescence = luminescence (transparent) = chemi + luminescence + chemi
The meaning is directly built from the combining form 'chemi-' (chemical) + 'luminescence' (light emission), yielding light produced by a chemical reaction.
Etymology
Chemiluminescence comes from two parts: chemi- (like the English word 'chemical') and luminescence (meaning 'light'). So, chemiluminescence literally means 'light from a chemical', which is why it describes light made by a chemical reaction without much heat.
