fat 词源(Etymology) - 趣词词源[英文版]

fat [fat 词源字典]: fat: [OE] Fat is one of a large Indo-European family of words denoting the substance ‘fat’ or its consequences in terms of obesity – the probably related Greek pímelē and Latin pinguis, for instance, signified respectively ‘lard’ and ‘fat’. The Germanic members of the family, which include German fett, Dutch vet, and Swedish fet as well as English fat, go back to a prehistoric Germanic *faitaz.
