The word 飞船 is formed by combining two characters: 飞 (fēi), meaning "to fly", and 船 (chuán), meaning "boat" or "ship". It is a direct and imaginative compound that creates a new concept by simply placing the action or characteristic ("flying") before the object ("ship"), resulting in the meaning "flying ship" or "airship". This structure visually and conceptually merges the two ideas to instantly convey the notion of a vessel that travels through the air, much like how one might intuitively describe such a vehicle in plain language.
