Where does prothesis come from?

From Late Latin prothesis, prosthesis, alteration (dropping the ‘s’) from Ancient Greek πρόσθεσις (prósthesis, “addition, augmentation”), (English prosthesis) from προστίθημι (prostíthēmi, “to add”), from πρός (prós, “towards”) + τίθημι (títhēmi, “to place”), from Proto-Indo-European *próti, *préti + *dʰédʰeh₁- (“to be putting, to be placing”). However, often confused for a descendant of the Ancient Greek word πρόθεσις (próthesis, “a preposing, preposition”) (without the σ (s)), which is instead the source of a different term – see alternative etymology, below.
