About
The character 堍 (tù) is a phono-semantic compound combining the semantic radical 土 (tǔ), meaning earth or land, with the phonetic component 兔 (tù), which indicates the pronunciation. Its meaning is specialized in civil engineering and geography, referring to the earthen approach or raised embankment at either end of a bridge. The earth radical thus reflects the material composition of these structures, and the character is used specifically to describe this component connecting a bridge to the surrounding ground.
