胶 means glue; gum; rubber.
As an HSK Level 5 character, 胶 is an intermediate-level character.
The character 胶 is a compound of the radical 月 (flesh/meat) and the phonetic component 交 (jiāo, meaning to cross or mix). Ancient glue was often made by boiling animal hides and bones, so the flesh radical reflects the material source, while 交 hints at the process of mixing or binding things together.
💡 Memory Tip: Imagine a piece of flesh (月) being crossed and bonded (交) with sticky glue that holds it together.

The left side is 月, the moon radical, but in this character it represents flesh or body parts (a variant of 肉). The right side is 交 (jiāo), which gives the sound and hints at connection or crossing. Together, they suggest something from the body (like animal hide) that is processed into a sticky substance used for bonding, which is glue.
