- a line of police, sentinels, military posts, warships, etc., enclosing or guarding an area.
- a cord or braid worn for ornament or as a fastening.
- a ribbon worn usually diagonally across the breast as a badge of a knightly or honorary order.
French for 'blue ribbon'. The Cordon Bleu was the highest order of chivalry under the Bourbon kings. It has since been used for other first-class distinctions. The term has migrated into the language as a figurative acclamation rather than actual decoration for high quality, especially for chefs.
