smorgasbord
Synonym discussion
Sense: noun/1
For food, smorgasbord overlaps with buffet, spread, feast, and banquet, but the tone is different. 'Buffet' is the most neutral word for a meal where people serve themselves, whether it is casual or formal. 'Smorgasbord' suggests a table crowded with many cold and hot choices and often sounds more colourful or slightly old-fashioned. 'Spread' is informal and focuses on the attractive amount of food laid out, even if people are not lining up to serve themselves. 'Feast' highlights abundance or celebration rather than the serving method. 'Banquet' is the most formal word and usually means a large ceremonial meal with seated guests. For a hotel breakfast, 'buffet' is normal; for a rich, overflowing display, 'smorgasbord' is more vivid.
Etymology
Borrowed from Swedish 'smörgåsbord', first naming a table set with bread, butter, fish, and other cold dishes. English kept the meal sense and later extended it to mean any rich mixed collection of things. The Swedish form joins 'smörgås' (an open sandwich or bread with toppings) and 'bord' (table).
