Etymology

牢 combines 宀 (roof/building) with 牛 (cow), originally depicting an enclosure for livestock. Over time it came to mean any confined space, especially a prison.

Meaning mnemonic

Under a roof (宀), a cow (牛) is penned in. Picture a sturdy barn that feels like a jail for the animal—牢 means prison or hardness.

Reading mnemonic

For ロウ, imagine a low, dark prison cell where the cow is kept: low -> ロウ, and the cow is locked up tight.
