Where the shape of 日 comes from

日 is a pictograph of the sun. Early forms show an outline with a dot or a short line in the middle. In today's script, written with straight strokes, the outline is a tall box and the mark is the line across the centre.

Why the mark is there is not certain. One common explanation is that it was added to tell the sun apart from other, similar-looking shapes.

The meaning "day" grew out of the meaning "sun".
