5. History
Liushu category: Pictogram (象形)
Origin: In Oracle Bone script, 日 was drawn as a circle with a dot or line inside to represent the glowing face of the sun.
Semantic Evolution: Originally representing the physical sun in the sky, it naturally extended to mean the duration of one daytime cycle (a day), then specific calendar dates, and eventually geographical abbreviations like Japan (the land of the rising sun).
The dot inside ancient pictographs gradually flattened into a horizontal line in standard clerical script for easier brush writing.
