köken: Borrowed from French buffet. The spelling Büfett, preferred at least in Germany, represents the Germanised pronunciation in /ɛt/. Such a pronunciation has established itself in many words like Parkett, Kabarett, etc. In the case of Buffet, however, the French pronunciation has widely prevailed, which means that speakers now often pronounce /eː/ while reading and writing Büfett.
Borrowed from Betawi prasmanan (“buffet”, literally “French style”), from Prasman (“French”) + -an, with the first element derived from Dutch Fransman (“Frenchman”). Alluding to service à la française, from which the buffet is derived.
