U+7DD8 "緘" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
緘
U+7DD8 "緘" CJK Unified Ideograph-# is a complex East Asian ideograph primarily used in Chinese, Japanese, and Korean writing systems, where it carries the core meaning of "seal" or "close." Historically composed of the silk radical on the left and a phonetic component on the right, the character evokes the image of tying or fastening something with thread, and by extension refers to sealing a letter, keeping silent, or restraining oneself. In modern usage, it appears in terms such as the Japanese word "chakurei" for ascetic silence and the Chinese word "jian mo" meaning to keep one's mouth shut, reflecting a conceptual emphasis on closure, confidentiality, and restraint.
