bomb: [17] Bomb is ultimately of onomatopoeic origin, and can probably be traced back to Greek bómbos, a word for a booming or buzzing sound. This passed into Latin as bombus, the probable source of Italian bomba, which acquired more explosive connotations. English got the word via French bombe. The derivative bombard preceded bomb into English, in the 15th century. => bound[bomb etymology, bomb origin, 英语词源]
