【引伸】
debunk.er
n.（名詞）
<注釋>One can readily see thatdebunk is constructed from the prefix de-, meaning .to remove,. and the wordbunk. But what is the origin of the wordbunk, denoting the nonsense that is to be removedô Bunk came from a place where much bunk has originated, the United States Congress.During the 'th Congress (89-82) Felix Walker, a representative from western North Carolina whose district included Buncombe County, continued on with a dull speech in the face of protests by his colleagues.Walker replied he had felt obligated .to make a speech for Buncombe..Such a masterful symbol for empty talk could not be ignored by the speakers of the language,andBuncombe, actually spelled Bunkum in its first recorded appearance in 828 and later shortened tobunk, became synonymous with claptrap. The response to all this bunk seems to have been delayed,fordebunk is not recorded until 923.
可以很容易地看出debunk 是由前綴 de-， 表.去掉.和單詞bunk 構成的。 可是單詞bunk 表示.要除去的無稽之談.的含意的起源是什么呢ô Bunk 來自美國國會，一個產(chǎn)生大量空話、假話的地方。在第'屆國會期間(89-82年），一個來自北卡羅來納州西部（其區(qū)域包括邦克姆縣）的代表費列克斯·沃爾克面對其同僚們的抗議，而進行持續(xù)冗長枯燥的演講，沃爾克說他有責任.為邦克姆發(fā)表演說.。這種說空話的杰作是不會被說英語的人忽視的。Buncombe 實際上在828年第一次被記載時拼作 Bunkum ， 后來縮寫成Bunk 并成為 claptrap 的同義詞。 對這空話的反應似乎被耽擱了，因為debunk 直到923年才被記錄下來
