About
苯 is a phono-semantic compound with the grass radical 艹 on top, indicating its plant-related meaning, and the phonetic component 本 below. In classical texts, it referred to a type of lush grass, but this sense is now obsolete. The character was later repurposed as a phonetic loan for the chemical benzene, adopting its modern scientific meaning based on pronunciation similarity to the English word, while its original botanical definition was abandoned.
