FromLate Latinprothesis,prosthesis, alteration (dropping the ‘s’) fromAncient Greekπρόσθεσις(prósthesis,“addition, augmentation”),[1][2][3] (Englishprosthesis) fromπροστίθημι(prostíthēmi,“I add”), fromπρός(prós,“towards”) +τίθημι(títhēmi,“I place”), fromProto-Indo-European*próti,*préti +*dʰédʰeh₁-(“to be putting, to be placing”).
However, often confused for a descendant of the Ancient Greek wordπρόθεσις(próthesis,“a preposing, preposition”) (without theσ(s)), which is instead the source of a different term – seealternative etymology, below.
