About
The character "氰" is a modern chemical coinage formed to translate the term "cyanogen", which itself originates from the Greek "kyanos" for blue. Its structure is a phono-semantic compound, combining the semantic radical "气" to signify a gaseous substance with the phonetic component "青", which approximates pronunciation and references the blue hue of certain cyanogen compounds. This character has consistently carried the specific meaning of cyanide-related chemicals since its creation for scientific terminology.
