The story of the word

In Greek ἀναλγησία could mean insensibility of the moral kind, a hardness that fails to feel for anyone else. Medicine kept only the physical half, and the surviving distinction is a useful one: an analgesic removes the pain, an anaesthetic removes the patient. The same ἄλγος hides inside nostalgia, which was coined for the ache of the return home.
