About

consists of the semantic radical (mouth) on the left and the phonetic component on the right. Like many characters coined for scientific translation, it was purposefully created to phonetically render a foreign chemical name rather than evolve from ancient natural observation. The radical often marks phonetic loans, and here exclusively denotes the organic compound indole in biochemical and pharmaceutical terminology.
