About
The character "泌" is structurally formed by the water radical combined with the phonetic component "必", a construction that from its inception signaled an association with liquids. Etymologically, it conveyed the broad notion of water flowing or seeping through, but its meaning gradually specialized to focus more narrowly on the act of secretion, particularly within organic systems. This semantic shift from a general hydraulic concept to a specific physiological term represents the primary evolution in its usage, while its graphic composition has remained consistent over time.
