Origin

This character combines a grass radical at the top with the component 監 (which means "to inspect" or "to oversee") at the bottom. The grass radical indicates this is a plant, while the lower component suggests something that was carefully observed or controlled. Together, they point to indigo—a plant whose leaves were cultivated and processed with careful attention to produce the valued blue dye used in Japanese textile work. The combination essentially describes indigo as a "watched plant" or "inspected plant," reflecting how important it was to monitor and harvest this plant correctly for dye production.
