U+55D2 "嗒" CJK Unified Ideograph-# Unicode Character

U+55D2 "嗒" CJK Unified Ideograph-# is a Chinese character (CJK, or Chinese, Japanese, and Korean) that primarily functions as an onomatopoeic word representing a sharp or tapping sound, such as a click, a crack, or the sound of a horse's hooves. In modern Chinese usage, it appears in words like “dāla” (耷拉) meaning to droop or hang down, though its phonetic component often conveys the idea of a sudden, crisp noise. The character is composed of the radical “口” (mouth/speech) on the left, indicating sound or spoken action, and the phonetic element “荅” (dá) on the right, which contributes to its pronunciation. It is encoded in the CJK Unified Ideographs block of Unicode, which consolidates historical and contemporary characters used across multiple East Asian writing systems.
