bread: [OE] The general Germanic word for ‘bread’ in prehistoric times was what we now know as loaf; bread probably originally meant simply ‘(piece of) food’, but as bread was among the commonest foods, the word bread gradually became more specialized, passing via ‘piece of bread’, ‘broken bread’, to simply ‘bread’. Old English brēad and related Germanic forms such as German brot and Swedish bröd point to a hypothetical Germanic precursor *brautham, but the word’s ultimate origins are unknown. Some etymologists have derived it from Indo- European *bhreu-, source of English brew. [bread etymology, bread origin, 英语词源]
