Word Origin:
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.).
