About

The traditional character 除 is composed of the left radical 阜, indicating a mound or steps, and the right phonetic component 余. Its original meaning was tied to the physical action of removing something, such as earth from a slope or steps ascending a hill, which is reflected in this structure. Over time, its meaning extended from literal removal to more abstract concepts of elimination, exclusion, and expulsion. In mathematics, it acquired the specific sense of division as a form of removal or partitioning. The character’s form remained largely consistent, and its semantic range broadened to include notions like "except" and "unless", deriving from its core idea of exclusion.
