About

The character (diū) is a modern addition to the Chinese lexicon, coined for the chemical element thulium, a rare earth metal with atomic number sixty-nine. It is a phono-semantic compound following the standard conventions of chemical nomenclature: the semantic radical (jīn), meaning 'gold' or 'metal', on the left classifies it as a metallic substance, while the phonetic component (diū) on the right gives the pronunciation, approximating the first syllable of the element's Latin or English name. The traditional form is , with the full metal radical . This character's meaning is singular and entirely chemical, illustrating how the script systematically incorporates modern scientific discoveries.
