About
The character "锩" is the simplified form of "鎸", which etymologically combines the metal radical 金 with the component 隽, indicating its association with engraving on metal. The meaning has consistently referred to carving or incising hard surfaces. In the simplified structure, the metal radical is represented by 钅, and 隽 is replaced by 卷, which provides a more direct phonetic indication while retaining the semantic focus on metalwork.
