ireful

This term describes a state of intense, often righteous or authoritative anger. It carries a heavier, more formal weight than "angry" and suggests a simmering or explosive wrath that is often directed from a position of power or perceived moral superiority.

Because of its archaic and literary tone, it is rarely used in casual conversation. It is most appropriate in historical narratives, epic poetry, or high-fantasy settings to evoke a sense of dramatic gravity and timelessness.
