Why “phrenitis” is a great word
A madness caused specifically by inflammation of the brain. From Latin *phrenītis*, from Ancient Greek *φρενῖτις* (*phrenîtis*), from *φρήν* (*phrḗn*, "mind, diaphragm") + *-ῖτις* (*-îtis*, "inflammation"). Unlike "frenzy," which is a wild abandonment of restraint, or "delirium," a transient confusion from myriad causes, phrenitis is an antique diagnosis of physical fire: the fever-cracked brow, the eyes too bright and hot, the body thrashing as if the organ of thought were aflame. It speaks of a time when madness was not merely metaphor but a felt pathology—the skull no longer a fortress but a pressure cooker, and thought itself become collateral damage of tissue in revolt.
