badger
貛 centers on the badger, a specific animal. The meaning is concrete and narrow, referring directly to the creature itself.
貛 combines the beast radical 豸 with the phonetic component 雚, which likely contributed the sound while 豸 indicates an animal. The exact historical development is uncertain, but the structure is a typical phono-semantic compound for an animal name.
The left side 豸 suggests a beast or animal with a long body, and the right side 雚 looks like a complex creature with a head, eyes, and tail. Picture a badger's distinctive striped face and stocky body in the tangled strokes.
For カン, imagine a badger carrying a can of food back to its den: can -> カン, and the badger is the animal 貛.
