'fling' originates from Old Norse, specifically the word 'flengja,' where 'flengja' meant 'to whip or lash.'

'flengja' transformed into the Middle English word 'flingen,' and eventually became the modern English word 'fling'.

Initially, it meant 'to whip or lash,' but over time it evolved into its current meaning of 'to throw or hurl with force.'
