'aeronautic' originates from the Greek word 'aeronautikos', where 'aero-' meant 'air' and 'nautikos' meant 'pertaining to ships or sailors'.

'aeronautikos' transformed into the French word 'aéronautique', and eventually became the modern English word 'aeronautic'.

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