惊慌失措
jīng huāng shī cuò · HSK 7
to lose one's head out of fear (idiom)
😱 惊 startled + 慌 panic + 失 lose + 措 plan = so scared you lose your plan of action
惊 — horse 马 + respect 敬 (phonetic)
Originally written 驚 with 馬 (horse) as the meaning component and 敬 as the phonetic, depicting a horse startled or frightened. The simplified form 惊 replaces 馬 with 忄 (heart radical), shifting the imagery to a startled mind. The core meaning is to be alarmed, surprised, or shocked.
慌 — heart radical 忄 + 荒 huāng (wild)
A semantic-phonetic compound: the heart radical 忄 gives the meaning (an emotional state), while 荒 supplies the sound huāng and a hint of 'wild, barren.' Originally suggesting a heart in disarray like wasteland, it came to mean flustered, panicked, or in a hurry.
