vinegaryoudaoicibaDictYouDict[vinegar 词源字典]
vinegar: [13] Etymologically, vinegar is ‘sour wine’. The term was borrowed from Old French vyn egre, whose elements went back respectively to Latin vīnum ‘wine’ (source of English wine) and acer ‘sharp, pungent’ (source of English eager). In modern French, vyn egre became vinaigre, and its diminutive form has given English vinaigrette [17]. This originally denoted a sort of small French carriage, which supposedly resembled a vinegar-seller’s cart; the modern application to an ‘oil-and-vinegar dressing’ is not recorded in English until the end of the 19th century.
