Etymology

From New Latin prostheticus, from Ancient Greek προσθετικός (prosthetikós, “adding; repletive; giving additional power”), from πρόσθεσις (prósthesis, “addition”), from προστίθημι (prostíthēmi, “I add”), from πρός (prós, “towards”) + τίθημι (títhēmi, “I place”). By surface analysis, prosth- + -etic.
