buffet
Synonym discussion
Sense: noun/1
For noun/1, a buffet is defined by the way people eat: dishes are set out together, and guests choose for themselves. A banquet is more formal and usually involves guests being served at tables. A feast stresses abundance and pleasure, and it does not have to be self-service. Smorgasbord is close to buffet, but it sounds more marked and often suggests a Scandinavian-style spread or a very wide mixed selection. A cafeteria is mainly a place or system for getting food along a counter, not a special social meal. Say 'The hotel offers a breakfast buffet,' but 'The city hosted a state banquet.'
Etymology
Modern English buffet brings together two older French lines. The noun for a serving table or sideboard came through French buffet, and from that base English later developed the meal and station-food senses. The verb comes from Old French buffeter, meaning to strike or slap. Over time, English kept both histories but wrote them with the same form, so the noun and verb look alike today even though they began separately.
