Here's a breakdown:
* Broadside: A formal and direct attack, usually delivered in a public setting. It often implies a strong, well-prepared criticism.
* Blast: A more casual and informal way to describe a verbal attack. It can be a sudden and intense outburst of criticism or anger.
Here are some examples:
* Broadside: "The politician delivered a scathing broadside against his opponent's policies."
* Blast: "The teacher gave the student a blast for not completing their homework."
So, while both terms refer to a verbal attack, "blast" is more informal and spontaneous, while "broadside" is more formal and planned.
