U+55DD "嗝" CJK Unified Ideograph-# Unicode Character
U+55DD "嗝" CJK Unified Ideograph-# is a Chinese character used in both traditional and simplified writing systems, primarily meaning "hiccup" or "belch." It belongs to the CJK (Chinese, Japanese, Korean) ideograph block and is composed of the mouth radical (口) on the left and the phonetic component "阁" or a similar sound element on the right, reflecting its oral nature. In everyday usage, it appears in contexts related to bodily functions, such as in medical descriptions or casual conversation about digestion, and it also extends metaphorically to describe small, sudden interruptions or pauses. This character has a long history in classical Chinese literature, where it documented physiological reactions, and it remains relevant in modern East Asian languages for its precise onomatopoeic quality.
