Indignation

IRE

Think of the intense anger often seen in fiery speeches or heated arguments—this four-letter word captures that burning resentment.

Indignation" is a strong feeling of anger or annoyance, often at something unfair. The answer "IRE" fits because it’s a concise literary or formal term for the same kind of anger—think of it as the fancier, shorter cousin of "wrath." You might see it in older texts or crosswords where brevity is key, like Shakespearean insults or classic poetry. No tricks here, just a direct synonym swap.
