wheel
About
The traditional character "轂" is structured with the semantic component "車" indicating its relation to vehicles and the component "殻" which provides phonetic guidance and conveys the idea of a hard casing. Its core meaning has consistently been the hub of a wheel, the part that surrounds and rotates on the axle. In classical Chinese literature, the term occasionally extended to refer to the wheel itself or was used metaphorically to denote a central point. The simplified form "毂" modifies the structure to "车" alongside "士" and "殳", yet continues to represent the same mechanical concept.
