noun, used as a suffix
fit of strong emotion; moment of intense feeling
Used as a suffix attached to emotion nouns (e.g., 怒り, 悲しみ, 悔しさ) to indicate being overcome by that feeling, often momentarily. Usually written in kana.
怒りまぎれに、ついひどいことを言ってしまった。
In a fit of anger, I ended up saying something terrible.
悲しみまぎれに、彼は部屋を飛び出した。
Overcome with grief, he rushed out of the room.
Derived from the verb 紛れる (まぎれる, 'to become mixed up, to be indistinguishable'). The suffix usage developed from the idea of being 'lost' in a strong emotion.
