About
The character "氟" is a relatively modern creation, coined in the scientific context of the 19th century to name the chemical element fluorine. Its traditional form, which remains in use, is a phono-semantic compound built from the semantic component 气, which denotes gases or vapors and categorizes the character within that domain, and the phonetic component 弗 (fú), which provides an approximate sound while also possibly alluding to the element's hazardous properties, as 弗 can carry a connotation of negation or prohibition. The etymology thus directly constructs the meaning of a gaseous element (气) with a name sounding like "fu" and characteristics that are negating or harmful. Unlike many characters with long histories, its meaning has not shifted since its inception, remaining exclusively tied to the chemical element and its compounds.
