Tips
history
磾 is not used independently in modern Chinese. It survives almost solely in the historical name 金日磾, a Han-dynasty statesman of Xiongnu origin. It joins the stone radical 石 (a mineral) with the phonetic 單 (simplified 单).
register
Archaic; encountered only in classical history and old names, not in modern Chinese. Note the name reading: the middle character is read mì and the last dī in 金日磾.
