いきり立つ

• 読み: いきりたつ
• ローマ字: ikiritatsu
• 漢字の分解: 立 (ritsu/ta) — stand, arise; いきり — heating up, agitation (native Japanese root)
• 発音: /i.ki.ɾi.ta.tsɯ/

意味

To get worked up; to fly into a rage; to bristle with anger or excitement. Describes a sudden surge of intense emotion, typically anger.

A Group 1 (godan) compound verb combining いきる (to become heated/tense) and 立つ (to stand up/arise). The whole verb suggests a person who abruptly rises up in agitation or fury. The tone is usually negative — an overreaction to a minor provocation. Occasionally used for intense excitement in non-angry contexts, but anger is by far the dominant nuance. More vivid and colloquial than 激怒する.

例文

1. 些細な一言にいきり立って怒鳴り散らすのは、大人げない振る舞いだ。
2. 判定に不満を持ったファンたちがいきり立ち、会場は一時騒然となった。
