'frolic' originates from Dutch, specifically the word 'vrolijk,' where 'vrol-' meant 'merry' and '-ijk' was a suffix for adjectives.

'vrolijk' transformed into the Middle English word 'frolic,' and eventually became the modern English word 'frolic.'

Initially, it meant 'merry or cheerful,' but over time it evolved into its current meaning of 'playful activity.'
