意味

至急で／火急に

火速 is an intensifying adverb meaning 'as fast as fire' — describing the extreme urgency with which something is done. It appears frequently in military, emergency, and official contexts: 火速赶赴现场 (rush to the scene with all urgency), 火速处理 (handle with immediate urgency), 火速支援 (rush support immediately). It conveys both speed and the critical importance of the situation.
