Bombardment comes from bombard + -ment. Bombard comes from French bombarder, from bombarde ('a siege cannon'), ultimately from Latin bombus ('booming sound'), from Ancient Greek bombos, of imitative origin. The historical trail runs through bombarder in French, bombus in Latin, and bombos in Ancient Greek. Morphologically, bombardment is transparent: it draws on bombard + -ment. Used as a noun, bombardment now means "a continuous attack with bombs, shells, or other projectiles", so the present definition can be read against the older forms and meanings. The same lexical family is also visible in related forms such as bombard, bombardier, and bomb. The result is a borrowed or transmitted form whose modern spelling carries a compact record of its route into English.
