'aeroplane' originates from French, specifically the word 'aéroplane', where 'aéro-' meant 'air' and 'plane' referred to 'flat surface'.

'aéroplane' transformed into the English word 'aeroplane' and eventually became the modern English word 'aeroplane'.

Initially, it meant 'a flat surface for flying', but over time it evolved into its current meaning of 'a powered flying vehicle'.
