About
The character "碘" is a relatively modern creation in the Chinese writing system, formulated specifically to denote the chemical element iodine after its isolation in the early 19th century. Its structure is a semantic-phonetic compound, combining the radical "石" meaning stone or mineral on the left to classify its inorganic nature, with the component "典" on the right which primarily serves a phonetic function, approximating the sound "dian". The meaning of the character has remained narrowly focused and stable since its inception, directly and exclusively referring to the element itself and its compounds, with no significant drift or expansion in its semantic use over time.
