U+7DAD "維" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
維
U+7DAD "維" CJK Unified Ideograph-# is a logogram used in Chinese, Japanese, and Korean, where it primarily means "to tie," "to maintain," "to preserve," or "to connect," and in a more abstract sense represents the concept of "dimension" or "link" as in the mathematical construct of a thread or fiber. In classical Chinese, it often appears in terms like "維持" (to maintain) or "維修" (to repair), and in Japanese it features in compounds such as "維新" (ishin, meaning "restoration"). Its radical is 糸 (silk, thread), reflecting its original significance related to binding or connecting strands, and it serves as a key component in many technical and philosophical expressions across East Asian languages.
