Morphology

retractile = retract (transparent) = retract + ile

The adjective is directly formed from the verb 'retract' with the adjectival suffix '-ile', conveying 'capable of being retracted'.

Etymology

Retractile comes from two parts, re- meaning 'back' and tract meaning 'pull', the same root you see in tractor. So, something retractile can be 'pulled back' into itself or into a cover, like a cat pulling its claws into its paws.
