Etymology

光 is a pictograph of a person kneeling under a flame or light source, representing light or radiance. The modern form retains the top ⺌ (a simplified fire/light element) and the bottom 儿 (legs), though the original kneeling figure is now stylized.

Meaning mnemonic

The top ⺌ looks like a small flame or light, and the bottom 儿 resembles legs. Picture a person holding up a light, making rays shine out: 光 is light.

Reading mnemonic

For コウ, imagine a bright light shining on a coal (コウ) mine: coal -> コウ, and the light illuminates the dark mine.
