About
The character "蕹" is structured as a phono-semantic compound with the grass radical "艹" positioned above the phonetic component "雍", indicating its classification as a plant while providing a cue to its pronunciation. Etymologically, this character was devised to denote the aquatic vegetable water spinach, and its semantic application has consistently been limited to this plant name in historical texts. The traditional form of the character retains this compositional arrangement without alteration.
