PeltRadical: Skin

pelt, skin, hide, leather, skin radical (no. 107)

Mnemonic

A comet blazes overhead, its fiery tail resembling a giant pelt stretched across the night sky. Below, a hunter uses a wooden rack to support the fresh pelt he's drying—as if mirroring that cosmic hide above. The comet's glow illuminates the raw animal skin perfectly.
Additional thoughts
Picture the comet's long tail as a huge animal hide unfurling across the heavens, while below a drying rack supports the real pelt. The parallel imagery locks comet + support = pelt together.
Quick recall
A comet's tail looks like a giant pelt in the sky, while a rack supports the real hide below.

Details

The keyword for 皮 is pelt. This kanji refers to the skin or hide of an animal, particularly one that has been stripped or peeled off. It conveys the idea of an outer covering or surface layer, much like the raw hide removed from an animal before it is processed into leather. By extension, it can also refer to any outer skin, rind, or bark that serves as a natural covering.
