Why “diadem” is a great word
A formal headband or crown worn as the emblem of royal authority. From Middle English diademe, from Old French diademe, from Latin diadēma, from Ancient Greek διάδημα (diádēma, "band, fillet"), from διαδέω (diadéō, "I bind around"). Unlike a "tiara," a decorative, often feminine ornament for state occasions, or a "coronet," a small crown denoting a specific, lesser rank of nobility, a diadem is the very symbol of sovereign power itself. It is the cold, encircling weight of gold pressing upon a monarch's brow, the glint of precious stones woven into a band of command, the silent, brutal geometry of a circle that binds a ruler to a realm—the ultimate jewelry of burden.
