Meaning & readings

genius, years old, cubic shaku

On’yomi サイ

Origin

This character most likely pictures a sprout or small plant pushing up from the ground, shown with a bent or curved stem. The connection to "genius" probably comes from the idea of natural talent naturally sprouting or growing, much like a young plant. Over time, the shape became more abstract and simplified into the three strokes we see today. The meaning "years old" may have developed as a secondary use, possibly because young growth also suggests youth or early age.
