About
The character 腽 is a phonetic-semantic compound formed with the flesh radical 月, denoting a connection to the body or fat, and the phonetic component 昷, which provides a cue to its pronunciation. It appears almost exclusively in the compound 腽肭, a term historically used for the sea otter or its pelt. The semantic choice of the flesh radical aligns with the animal's corpulent physique, and the character has maintained this highly specialized meaning since its creation without expanding into other semantic domains.
