Etymology

The noun is borrowed from Latin corōna (“crown; garland, wreath”), from Ancient Greek κορώνη (korṓnē, “type of crown; curved object (door handle, tip of a bow, stern of a ship, etc.)”), from Proto-Indo-European *(s)ker- (“to turn, bend”). The English word is a doublet of crown, korona, koruna, krona, króna, and krone. The plural form coronae is borrowed from Latin corōnae. The verb is derived from the noun.
