'unwind' originates from Old English, specifically the word 'unwindan,' where 'un-' meant 'reverse' and 'windan' meant 'to wind.'

'unwindan' transformed into the Middle English word 'unwinden,' and eventually became the modern English word 'unwind.'

Initially, it meant 'to undo something wound,' but over time it evolved to include the meaning of 'relaxing or de-stressing.'
