'walk' originates from Old English, specifically the word 'wealcan', where 'wealcan' meant 'to roll or toss'.

'wealcan' transformed into the Middle English word 'walken', and eventually became the modern English word 'walk'.

Initially, it meant 'to roll or toss', but over time it evolved into its current meaning of 'to move at a regular pace by lifting and setting down each foot in turn'.
