'aeronautically' originates from the Greek word 'aeronautikos', where 'aero-' meant 'air' and 'nautikos' meant 'of ships or sailors'.

'aeronautikos' transformed into the French word 'aéronautique', and eventually became the modern English word 'aeronautical' through Middle English.

Initially, it meant 'related to air navigation', but over time it evolved into its current meaning of 'related to the science or practice of building or flying aircraft'.
