Morphology

retardant = retard (transparent) = retard + ant

Clear derivation from the verb 'retard' with the adjectival/agentive suffix '-ant', meaning 'a substance that retards'.

Etymology

The word retardant comes from an old Latin word that means 'slow' and it shares the same root as the English word tardy, which means 'late'. So a retardant is something that 'makes slow' a process, for example a chemical that slows down a fire.
