Etymology

非 is a pictograph of two opposing wings or a divided shape, representing opposition or negation. The modern form retains the symmetrical, split appearance that suggests something contrary or wrong.

Meaning mnemonic

The two sides of 非 look like mirror images that are slightly off, like a mistake or something that is not right. Picture two wings flapping in opposite directions, symbolizing negation and injustice.

Reading mnemonic

For ヒ, imagine a person saying "he" is wrong: "he" -> ヒ, and the mistake is clear in the opposing wings of 非.
