About
The character "苯" originally functioned as a descriptive term for thick or luxuriant grass, a sense derived from its structural composition which places the grass radical atop the component "本", meaning root or source. Its classical usage was infrequent and narrowly applied to botanical descriptions, but the character experienced a substantial semantic shift during the period of scientific lexical borrowing, when it was adopted to translate the organic chemical compound "benzene". This reassignment was primarily phonetically motivated, with "本" approximating the "ben-" sound, while the grass radical provided a tenuous link to organic origins, thereby transforming the character from an obscure poetic adjective into a precise scientific term central to modern chemistry.
