Etymology

紂 combines 糸 (thread) with 寸, which may have contributed a phonetic element. The exact historical development is uncertain, but the character is associated with a leather strap, suggesting a connection to binding or tying.

Meaning mnemonic

The left side 糸 suggests thread or cord, and the right side 寸 looks like a hand measuring. Imagine a leather strap measured and threaded under a horse's tail to secure the harness.

Reading mnemonic

For チュウ, picture a horse chewing on its harness strap: chew -> チュウ, and the strap keeps the harness in place.
