The word "泾源" is formed by combining the character "泾", a phono-semantic compound where "水" (water) is the semantic component indicating association with a river, specifically the Jing River, and "巠" serves as the phonetic component, with the character "源", also a phono-semantic compound where "水" (water) is the semantic component related to water and "原" acts as the phonetic component while contributing to the meaning of "source" or "origin"; together they create a compound word that literally means "source of the Jing River", used as a place name.
