red herring (n.)
"熏鲱鱼"早在15世纪就出现了(在腌制时会变成红色),与 white herring "新鲱鱼"相对。据说是逃亡者用来蒙混血猎犬的(1680年代),因此在1864年引申为“用来转移注意力的东西”的比喻意义; 早期它只是指“一个错误的线索”:
Though I have not the honour of being one of those sagacious country gentlemen, who have so long vociferated for the American war, who have so long run on the red-herring scent of American taxation before they found out there was no game on foot; (etc.) [Parliamentary speech dated March 20, 1782, reprinted in "Beauties of the British Senate," London, 1786]
虽然我没有成为那些聪明的乡绅之一,他们已经长时间高呼要进行美国战争,他们在发现没有目标之前已经长时间追踪美国税收的红鲱鱼的气味; (等等)[议会演讲日期为1782年3月20日,收录于“英国参议院之美”,伦敦,1786年]
