The Full Story
Greek18th centurywell-attested
From Greek 'prosthesis' (an addition, an attachment, a placing in addition), from 'prostithenai' (to add to, to place upon, to put to), composed of 'pros-' (toward, in addition to, near) + 'tithenai' (to place, to put, to set), from PIE *dʰeh₁- (to put, to place, to make). A prosthetic is literally 'something placed in addition' — an artificialpart added where the original is missing, restoring what has been lost by placing something new in its position. The word entered English first as a grammatical term in the sixteenth century: in linguistics, 'prosthesis' or 'prothesis' denotes the addition of a sound or syllable to the beginning
away), and 'theme' (something set down). The same root through Latin 'facere' yielded 'fact,' 'factory,' 'fashion,' 'defeat,' 'effect,' and 'perfect.' Prosthetic thus shares its deepest root with both philosophical 'thesis' and practical 'factory' — all acts of placing and making. Key roots: pros- (Greek: "toward, in addition to"), *dʰeh₁- (Proto-Indo-European: "to put, to place, to make").
