'frenzied' originates from Middle English, specifically the word 'frenesie,' where 'frenesie' meant 'delirium or madness.'

'frenesie' transformed into the modern English word 'frenzied' through the influence of Old French 'frenesie.'

Initially, it meant 'delirium or madness,' but over time it evolved into its current meaning of 'wild excitement or uncontrolled activity.'
