About
The character "轳" is the simplified form of the traditional character "轤", both used exclusively in the compound "辘轳" to denote a windlass or pulley. Its structure follows the phono-semantic pattern, with the radical "车" indicating a connection to vehicles or mechanical devices and the component "卢" serving as a phonetic clue for its pronunciation. The traditional form "轤" similarly combines the semantic element "車" with the phonetic element "盧". Historically, the character has appeared in Chinese texts since the medieval period with its meaning consistently fixed on the well-wheel mechanism, without developing additional semantic uses.
