<注释>The word forcockroach in Spanish is cucaracha, which should certainly set anyone with an eye for etymology to thinking.Users of English did not simply borrow the Spanish word, however.Instead, they made it conform in appearance to other English words:cock, the word for rooster, and roach, the name of a fish. We do not know exactly why these words were chosenother than their resemblance to the two parts of the original Spanish word.We do know that the first recorded use of the word comes from a '24 work by the colonist John Smith.The form Smith used,cacarootch, is closer to the Spanish. A form more like our own,cockroche, is first recorded in '57. cockroach 一词在西班牙语中是 cucaracha ， 这当然使人们去思考语源。然而英语使用者不轻易地借用西班牙词。相反的，他们使它与其他英语单词的外形一致：cock ，意为公鸡的单词，以及 roach ，鱼的名称。 我们完全不知道这些单词是如何选择的，而不像西班牙原单词的两个部分。我们的确知道首次有记录使用该单词是在自由移住民约翰·史密斯'24年的作品中。史密斯使用的形式是cacarootch， 接近于西班牙语。 更加像我们自己的形式的cockroche ，在'57年首次有记录
