About
The character "菥" is a phono-semantic compound formed by the grass radical 艹, denoting its association with plants, and the phonetic component 析, which indicates its pronunciation. It has historically been used to designate the plant "菥蓂" (thlaspi), a usage found in traditional botanical and medicinal texts. The meaning of the character has remained specifically linked to this plant, without evidence of semantic expansion or shift. Its structural composition, with the grass radical and phonetic element, has been consistent in its recorded instances.
