NOTES
“Abracadabra,” says the magician, unaware that at one time the thing to do with the word was wear it, not say it.Abracadabra   was a magic word,the letters of which were arranged in an inverted pyramidand worn as an amulet around the neck to protect the wearer against disease or trouble.One fewer letter appeared in each line of the pyramid,until onlya  remained to form the vertex of the triangle. As the letters disappeared, so supposedly did the disease or trouble.While magicians still useabracadabra  in their performances, the word itself has acquired another sense, “foolish or unintelligible talk.”
    巫师没意识他所说的“Abracadabra”一词曾一度只是被用来佩带，而不是谈及。Abracadabra  是一巫术用语，其字母可被排成倒金字塔形，当作护身符戴在脖子上可保护佩戴者免除疾病和灾难。金字塔形的每一行少一个字母，直到三角形顶端只剩a 一个字母。 当字母消失时，疾病和灾难也被认为是消失了。但现在的巫术师在表演时仍使用abracadabra ， 于是这个词就带上了另一种意义，“愚蠢或无意义的话语”
