'freestyle' originates from English, specifically the combination of 'free' and 'style', where 'free' meant 'without restriction' and 'style' referred to 'a manner of doing something'.

'freestyle' evolved from the concept of 'free style' in sports, particularly swimming, where competitors were allowed to use any stroke.

Initially, it meant 'a style without restrictions', but over time it evolved into its current meaning of 'a category of competition or performance without set rules'.
