About
The character "腈" is a modern phono-semantic construct developed for scientific terminology, specifically to represent the chemical group known as nitriles, with its semantic component "月" indicating an organic substance and its phonetic component "青" approximating the sound of the Western term. Its structure adheres to the common Chinese compositional principle of combining meaning and sound, and as a relatively recent coinage for technical use, its meaning has remained fixed within the domain of chemistry without historical deviation.
