How did the word bomb come into usage?
A bomb is an explosive device which, although not containing more energy than ordinary fuel (except in the case of a nuclear weapon), generates and releases its energy very rapidly, as a violent, destructive shock wave. It is usually some kind of container filled with explosive material, designed to cause random destruction when set off. The word comes from the Greek βόμβος (bombos), an onomatopoetic term with approximately the same meaning as “boom” in English.
