About
The character 垸 is a phono-semantic compound composed of the semantic radical 土, denoting earth, and the phonetic component 完, which suggests its pronunciation. Its original meaning centered on an earthen embankment or dyke constructed for flood control and land reclamation, reflecting a practical application in hydraulic engineering. Over centuries, the term developed a specialized sense as a unit of measurement for lacquer or paste, a semantic shift that likely originated from the association of a rounded, completed form with the vessels used in such quantification. The structural composition of the character has not undergone alteration, with its elements consistently representing both meaning and sound.
