U+55DA "嗚" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

嗚

U+55DA "嗚" CJK Unified Ideograph-# is a traditional Chinese character that primarily functions as an onomatopoeic or interjectory expression, often used to represent the sound of sobbing, sighing, or a low mournful cry, or the roaring of wind and other natural elements. In Classical Chinese and literary contexts, it can also appear in the lamentation phrase "嗚呼" (wū hū), meaning "alas" or "oh dear," conveying a sense of grief or regret. The character is composed of the "mouth" radical (口) on the left, indicating its connection to vocal sounds, and the phonetic component "烏" (wū) on the right, which suggests its pronunciation and originally referred to a crow. As part of the CJK (Chinese, Japanese, Korean) unified ideographs, it is used across multiple East Asian writing systems with similar meanings.
