'anorexia' originates from Greek, specifically the word 'anorexia,' where 'an-' meant 'without' and 'orexis' meant 'appetite.'

'anorexia' changed from the Greek word 'anorexia' and eventually became the modern English word 'anorexia.'

Initially, it meant 'lack of appetite,' but over time it evolved into its current meaning of 'a medical condition characterized by an intense fear of gaining weight.'
