marmalade: [16] The word marmalade originally denoted ‘quince jam’. It comes via French from Portuguese marmelada, a derivative of marmelo ‘quince’. And marmelo goes back via Latin melimēlum to Greek melímēlon, a term meaning literally ‘honeyapple’ which was applied to the fruit of an apple tree grafted on to a quince (the second element, melon ‘apple’, is the source of English melon). Not until the 17th century was marmalade used for a preserve made from citrus fruits. => melon[marmalade etymology, marmalade origin, 英语词源]
