Why “dementate” is a great word
DEMENTATE — [Adjective, Verb] Deprived of reason; insane; to render someone so. From the Latin dēmentātus, perfect passive participle of dēmentō ("to drive mad, to be mad"), from dē- ("away from, out of") and mēns ("mind"). First attested in English in 1628. Unlike "demented," which suggests a settled, chronic unsoundness, or "deranged," which implies a perilous disordering, dementate speaks of a more absolute, classical exile from sanity. It is the glassy, uncomprehending stare of a monarch who has outlived his century, the feverish scrawl of a scholar who has deciphered a truth too vast for a single brain to hold, and the quiet, final click of a latch behind a door through which you cannot return—the formal recognition that the self has been evicted from its own house.
