About
The character "胍" is a phono-semantic compound composed of the semantic component "月", denoting organic matter or flesh, and the phonetic component "瓜", which indicates its reading. It was created to represent the organic compound guanidine, with its etymology traced to the Greek word "guanos" meaning dung, due to the compound's initial isolation from guano. The character's meaning has been consistently specialized for this chemical referent since its adoption into scientific terminology, without broadening or diverging into other semantic areas.
