jumbo 巨型的,大型客机
来自Jumbo,19世纪末伦敦动物园一头大象的名字,可能来自西非某语言。由于该大象异常巨大且如此知名,因此引申词义巨大的,巨型的,并用于指大型客机,特别是波音747.
"I tell you conscientiously that no idea of the immensity of the animal can be formed. It is a fact that he is simply beyond comparison. The largest elephants I ever saw are mere dwarfs by the side of Jumbo." [P.T. Barnum, interview, "Philadelphia Press," April 22, 1882]As a product size, by 1886 (cigars). Jumbo jet attested by 1964.
