The story of the word

Greek doctors used σκληρός for hard swellings and stiff joints; the tidy disease label ending in -osis is nineteenth-century clinical bookkeeping. Jean-Martin Charcot described sclérose en plaques in 1868, the scattered hardened patches that give multiple sclerosis its name. The same root sits in scleroderma, hard skin, and in the sclera, the tough white coat of the eye.
