About
The character 轳 (traditional form 轤) is a phono-semantic compound, with the semantic radical 车 (vehicle) indicating its connection to wheels or machinery, and 卢 providing the phonetic element. It appears almost exclusively in the compound word 辘轳, meaning a windlass or pulley system used for drawing water or hoisting heavy objects. Due to this restricted usage, 轳 has few independent meanings or metaphorical extensions, and its structure directly reflects its association with rotating mechanical devices in traditional engineering.
