U+7EBD "纽" CJK Unified Ideograph-# Unicode Character

U+7EBD "纽" CJK Unified Ideograph-# is a Chinese character that primarily means "knot" or "button," and it also conveys the concept of tying, binding, or connecting, as seen in its use in words like 纽带 (niǔ dài) meaning "bond" or "link." Composed of the radical 纟 (silk) on the left, indicating its association with threads or textiles, and the phonetic component 丑 (chǒu) on the right, this character is commonly used in modern Chinese to refer to buttons on clothing, as in 纽扣 (niǔ kòu), as well as to mechanical or relational connections, such as 枢纽 (shū niǔ) meaning "hub" or "pivot." Its historical and linguistic role underscores how a simple visual metaphor for tying silk has expanded to describe both physical fasteners and abstract relationships.
