trifle: [13] Trifle was acquired from Old French truffle, a derivative of truffe ‘trickery, deceit’ (it is not known where this came from; it has no connection with English truffle, which may come ultimately from the same source as tuber). The first record of its application to a ‘sweet dessert confection’ dates from the end of the 16th century. [trifle etymology, trifle origin, 英语词源]
