'demise' originates from Old French, specifically the word 'demis,' where 'de-' meant 'away' and 'mettre' meant 'to put.'

'demis' transformed into the Middle English word 'demise,' and eventually became the modern English word 'demise.'

Initially, it meant 'to put away or transfer,' but over time it evolved into its current meanings of 'death' and 'end of an institution.'
