Word Origin for prosthesis
1550s, "addition of a letter or syllable to a word," from Late Latin, from Greek prosthesis "addition," from prostithenai "add to," from pros "to" + tithenai "to put, place" (see theme). Meaning "artificial body part" is first recorded c.1900, from earlier use to describe the medical art of making artificial limbs (1706), on notion of "that which is added to" the injured body.
1837 in grammar; 1902 in the surgical sense, from Latinized form of Greek prosthetikos "disposed to add," from prosthetas "added," verbal adjective of prostithenai "to put to, add to" (see prosthesis). Related: Prosthetically.
