1. (architecture) A horizontal architectural element of a building, projecting forward from the main walls, originally used as a means of directing rainwater away from the building's walls.Examples: "It is a large square structure, two and a half stories in height, with a hipped roof rising above a handsome cornice with prominent modillions and surmounted by a balustraded belvedere."

2. (architecture) A decorative element applied at the topmost part of the wall of a room, as with a crown molding.Examples: "That ceiling was covered with square compartments,[...] It was supported by a gilded cornice, carved into a thousand curious shapes and emblems, among which the horned wolf, the crest of the Avonleigh family, was conspicuous."; "Challenger looked up at the cornice and round at the skirting."; "The half-dozen pieces […] were painted white and carved with festoons of flowers, birds and cupids. […] The bed was the most extravagant piece. Its graceful cane halftester rose high towards the cornice and was so festooned in carved white wood that the effect was positively insecure, as if the great couch were trimmed with icing sugar."

3. (furniture) A decorative element at the topmost portion of certain pieces of furniture, as with a highboy.Examples: "And blood was on the roof, and great gouts of blood on the walls and on the cornice of my bed."
