'deranged' originates from French, specifically the word 'déranger,' where 'dé-' meant 'away' and 'ranger' meant 'to arrange.'

'déranger' transformed into the English word 'derange,' and eventually became the modern English word 'deranged.'

Initially, it meant 'to disturb the order,' but over time it evolved into its current meaning of 'mentally disturbed.'
