About
The character 砝 is a phono-semantic compound formed by the semantic radical 石, which indicates a connection to stone or minerals, and the phonetic component 去, which provides its pronunciation. Historically, it represents the standard weights used with a balance scale to measure the mass of objects. Since early counterweights were often carved from stone or metal for accuracy, the stone radical reflects the material composition of these tools. Unlike characters that develop multiple meanings, 砝 remains specific to the technical domain of measurement, most commonly appearing in the compound 砝码 to denote the weights themselves.
