prosthetic

The word 'prosthetic' originates from the Greek 'prosthetikos', meaning "adding, affixing". This derives from 'prosthesis' (πρόσθεσις), a noun formed from the prefix 'pros-' ("to, in addition") and the root 'thesis' ("a placing, setting"), from the verb 'tithenai' ("to put, to place"). The literal sense of "adding something on" evolved in medical terminology to specifically denote the addition of an artificial device to the body. The modern abstract meaning retains this core logic of an external object being placed or attached to compensate for a missing internal part.
