About
The character "坍" is a phono-semantic compound formed by the earth radical 土, which semantically grounds it in concepts related to soil and terrain, and the component 丹, primarily functioning as a phonetic element to guide its pronunciation. Its etymology consistently associates it with the collapse or sinking of earth, as evidenced by its long-standing use to describe landslides, eroding banks, or the failure of structures built from soil. The meaning has remained stable over time, narrowly focused on physical collapse without expanding into metaphorical domains, while its structural composition has persisted without alteration, reflecting a direct and unchanged link between its written form and the idea of terrestrial disintegration.
