Attacking something with continuous force or rapid succession, originally with artillery or bombs.
From French 'bombarde' (early cannon) from Latin 'bomba' (sound of a bomb, from Greek 'bombos' meaning booming sound). Originally literal warfare, now metaphorical for overwhelming attacks.
The onomatopoeia root 'bombos' shows ancient people imitating sounds to name things—'bomb' came from trying to describe the boom they made, and the word's sound still matches its meaning perfectly.
