U+81A0 "膠" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
膠
U+81A0 "膠" CJK Unified Ideograph-# is a Chinese character traditionally used to represent glue, adhesive, or the process of sticking things together, often associated with materials like gum or resin. It is composed of the radical for "meat" or "flesh" on the left, suggesting a bodily or organic substance, and a phonetic component on the right that hints at its pronunciation, typically read as jiāo in Mandarin. Beyond its literal meaning, it also appears in compounds related to adhesion, such as in the term for "rubber" or "plastic," and has historical significance in traditional Chinese crafts and medicine where natural adhesives were derived from animal hides or plants.
