来自意大利语 rocchetto,纺纱轴,纺锤,烟花,火箭,来自 Proto-Germanic*rukkon,摇晃,纺 纱,来自 PIE*rug,纺纱,词源同 rock.-etto,小词后缀。比喻用法,因烟花,火箭形似纺锤体 而得名。
It passed into Italian as ruca, whose diminutive form ruchetta developed a variant rochetta – whence French roquette and finally English rocket [16]. Rocket ‘projectile’ [17] is ultimately an allusion to the shape of such objects. It comes via Old French roquette from Italian rocchetto, a diminutive form of rocca ‘spool’ – hence the application to the ‘cylindrical’ rocket. Rocca itself represents a borrowing from a prehistoric Germanic *rukkon, which also lies behind English ratchet.
Originally "fireworks rocket," meaning "device propelled by a rocket engine" first recorded 1919; rocket-ship in the modern sense first attested February 1927 ("Popular Science"); earlier as a type of naval warship firing projectiles. Rocket science in the figurative sense of "difficult, complex process or topic" is attested by 1985. Rocket scientist is from 1952.
That such a feat is considered within the range of possibility is evidenced by the activities of scientists in Europe as well as in America. Two of them, Prof. Herman Oberth and Dr. Franz Hoeff, of Vienna, are constructing a five-ton rocket ship in which they hope to reach the moon in two days. ["Popular Science," Feb. 1927]
