Etymology
About
蘁 is a phono-semantic compound with the grass radical 艹 on top, indicating its botanical category, and 惡 below as the phonetic element. The radical connects it to herbaceous plants, while 惡, though meaning "evil" or "dislike" independently, primarily provides the pronunciation here. Its presence may also subtly suggest the plant’s historically undesirable or invasive character.
