<注釋>The crocodile may owe its name to its resemblance to a much smaller creature, a lizard that lived in the stone walls of Ionia.This lizard`s name,krokodilos, is thought to be a compound of krokô, .pebble, gravel,. and drilos, which is only attested as meaning .circumcised man. but is assumed to mean .worm. as well. According to Herodotus, Ionians in Egypt noted the resemblance, probably humorously, between basking crocodiles and their own .worm of the stones..The modern form of Englishcrocodile represents a return to the Classical Latin spelling crocodolus, Latin having borrowed the word from Greek.But other spellings occurred in Classical Greek and Latin, and one of these Latin spellings,cocodrillus, passed into Medieval Latin and Old French (cocodril ) and then into English, so that our earliest possible use of the word, in a work perhaps composed before 300, is spelledcokedrille. It was not until the 'th century that the word came to have its present spelling.The various spellings met with in the history ofcrocodile reflect the same sort of variations that occurred in the history of alligator.
鱷魚可能是因?yàn)榕c一種比它小得多的生物，即生長在愛奧尼亞的石墻中的蜥蜴外表相似而得名。這種蜥蜴的名字krokodilos 被認(rèn)為是由 kroke （意為.卵石，礫石.）一詞和 drilos 這一（只被證明有.受割的人.的意思但又被假定有.蠕蟲.的意思的）詞組成的復(fù)合詞。 希羅多德認(rèn)為，埃及境內(nèi)的愛奧尼亞人可能出于幽默而記下了曬太陽的鱷魚和他們本地的.石頭中的蠕蟲.之間的類似點(diǎn)。英語的crocodile 的現(xiàn)代形式反映了古拉丁語拼法 crocodilus 的回歸， 拉丁語中的這個(gè)詞是從希臘語中引入的。但是出現(xiàn)在古希臘語和古拉丁語中的其它拼法以及其中一種拉丁語拼法，cocodrillus ， 卻進(jìn)入到中世紀(jì)拉丁語和古法語(cocodril )中，然后又進(jìn)入到英語中， 所以出現(xiàn)在可能寫于300年以前的一篇文章中的我們最早有可能使用該詞時(shí)的拼法是cokedrille 。 直到'世紀(jì)，這個(gè)詞才變成現(xiàn)在這種拼法。在crocodile 一詞的演變歷史中的多種拼法也反映了在 alligator 一詞的演變歷史中的相似變化
