Origin

This character combines the gate radical 門 with the component 兌. The gate suggests a checkpoint or boundary where things are examined and controlled. The 兌 component relates to exchange or transfer of goods. Together, they evoke the image of items passing through a gate for inspection—the essential idea behind reviewing or inspecting something. Over time, this visual metaphor of scrutiny at a gateway expanded to mean examination and revision more broadly.
