The story behind the word. Derived from Latin 'fanum' (temple or sacred place). In ancient Rome, 'fanaticus' described people who suffered violent, ecstatic frenzies while worshipping at a temple, perceived as being possessed by a deity. By the 17th century, it shifted in English to describe wild political or religious enthusiasm.
