About
The character "莨" is structured as a phono-semantic compound with the grass radical "艹" signifying its botanical category and the component "良" acting as a phonetic indicator for readings like "làng" or "liáng". Originally representing plants in a broad sense, its meaning later narrowed to designate specific species, such as the toxic herb henbane in the compound "莨菪" and the tuber used for dye in "薯莨". This semantic specialization from a general plant term to precise botanical references illustrates the character's developmental path without alteration to its fundamental composition.
