About
The character "宕" is composed of the roof radical "宀" over the component "石" for stone, a structure that points to its original meaning of a cave or stone house. This etymological foundation supported a semantic expansion where "宕" acquired the sense of delay or postponement, evident in compounds like "延宕", and also came to denote a flowing or unrestrained quality, as seen in "跌宕". These shifts in meaning transitioned from a concrete architectural reference to abstract concepts involving temporality and movement.
