Etymology

亥 is an ancient pictograph representing a boar or hog, used as the twelfth zodiac sign. The modern form is highly stylized, and the exact visual connection to the animal is no longer obvious.

Meaning mnemonic

The top 亠 looks like a roof, and the bottom 人 suggests a person. Imagine a person under a roof at night (9–11 PM), counting the hours until the boar sign arrives.

Reading mnemonic

For ガイ, picture a guy dressed as a boar for a zodiac festival: guy -> ガイ, and the boar sign is the guest of honor.
