When you see the word buffet, it's hard not to think "all-you-can-eat." Although the noun can refer to food set out for self-service, buffet also means "a blow, especially with the hand" or, as a verb, "to strike sharply."
The two meanings of buffet come from very different sources. The self-serve meal buffet — from 18th century French and pronounced buh-FAY — is named after a piece of furniture, bufet ("sideboard"), on which such a meal might be served. The meaning of hitting, however, comes from the Old French word bufe, "a blow" or "a puff of wind," and is pronounced BUH-fit. If the wind buffets the windows of your house, it can make them rattle in their frames, and if you are buffeted by bad news, you might shake in your shoes.
