（亦作-ise）verb词源
mid 16th cent. (as an adjective)： from French fanatique or Latin fanaticus 'of a temple, inspired by a god', from fanum 'temple'. The adjective originally described behaviour or speech that might result from possession by a god or demon, hence the earliest sense of the noun 'a religious maniac' （mid 17th cent.）.
