A small piece of bread or cracker topped with a spread or other appetizer; a bite-sized hors d'oeuvre.
From French 'canapé,' from canape (sofa or couch), because the topping sits atop the bread base like cushions on furniture. Entered English via 19th-century culinary French.
Canapé is named after a sofa—imagine describing food by furniture! French chefs literally called tiny appetizers 'little couches' because of how toppings rest on bread, and the metaphor stuck.
