Why “prosthesis” is a great word
An artificial device designed to replace a missing body part, either internally or externally. From Latin, from Ancient Greek πρόσθεσις (prósthesis, "addition"), from προστίθημι (prostíthēmi, "to add"), from πρός (prós, "towards") + τίθημι (títhēmi, "to place"); first attested in English in the 1550s in a grammatical sense. Unlike an orthosis, which supports an existing limb, or an implant, which may serve a function deeper within the body's landscape, a prosthesis is an unequivocal substitution. It is the carbon-fiber blade of a sprinter bending into the starting blocks, the precise grip of a myoelectric hand around a coffee mug, the glass eye that catches the light and almost seems to blink—a stranger's materials pressed into loyal service, negotiating a new and functional whole.
Etymology
Via Latin, from Ancient Greek πρόσθεσις (prósthesis, “addition”), from προστίθημι (prostíthēmi, “to add”), from πρός (prós, “towards”) + τίθημι (títhēmi, “to place”), from Proto-Indo-European *próti, *préti + *dʰédʰeh₁ti (“to be putting, to be placing”). By surface analysis, prosth- + -esis.
