badger
貉 refers to a badger, a specific animal. The meaning is straightforward and does not extend to abstract concepts.
貉 combines 豸 (a beast or animal radical) with 各, which likely contributes a phonetic element. The character is used for the badger, but the exact historical development of the components is uncertain.
The left side 豸 suggests a furry animal, and the right side 各 looks like a creature with a mouth and legs. Picture a badger emerging from its burrow: 貉 is the badger.
For カク, imagine a badger wearing a small cap (カク) as it digs: cap -> カク, and the badger's headgear helps you remember the reading.
