Origin

This character combines the bow radical on the left with a component on the right that suggests extending or reaching. The bow's curved shape naturally suggests something that stretches or spreads outward, and when paired with the right component, the combination came to express the idea of something growing or extending further. Over time, this visual sense of "spreading more and more" evolved into the abstract meaning of "all the more" or "increasingly." The native reading "iyoiyo" literally means "more and more," which closely captures how the character's visual structure suggests progression and expansion.
