'acrobatical' originates from the Greek word 'akrobatos', where 'akro-' meant 'high' and 'batos' meant 'walking'.

'akrobatos' transformed into the French word 'acrobate', and eventually became the modern English word 'acrobatical' through Middle English.

Initially, it meant 'walking on tiptoe or high places', but over time it evolved into its current meaning of 'relating to acrobatic skills'.
