About
The character 铊, with its traditional form 鉈, is a phono-semantic compound comprising the metal radical 钅, derived from 金 in the traditional form, and the phonetic component 它. Initially, this character referred to a type of spear or dagger, a meaning derived from its metal radical indicating a weapon made of metal. Over centuries, its application shifted, and by the modern era, 铊 was adopted to denote the chemical element thallium, a soft, heavy metal discovered in the 19th century, with the metal radical appropriately categorizing it as a metallic substance and the phonetic 它 suggesting its pronunciation as tā.
