non.chalant.ly
adv.（副词）<注释>A nonchalant person is not likely to become warm or heated about anything,a fact that is underscored by the etymology of the wordnonchalant. Non-,the first part of the word, is easy to spot as a familiar negative prefix;since this word was formed in Old French,we havenon-, the Old French descendant of Latin nôn-. The second element,chalant, is the Old French present participle of the verb chaloir, meaning .to be concerned..This in turn came from the Latin wordcalôre, which from its concrete sense .to be hot or warm. developed the figurative sense .to be roused or fired with hope, zeal, or anger..Obviously the Old French verbchaloir has lost some of the warmth of Latin calôre, but then, the nonchalant person has little warmth or concern.The wordnonchalant is first recorded in English before 734, although Frenchnonchalance, a derivative of French nonchalant, seems to have entered English first. Englishnonchalance is first recorded in '78. 态度冷漠的人是不太可能变得热心或对某事激动的，这一事实被词语nonchalant的词源所强调。 Non-，这个词的第一部分， 很容易认出是个很熟悉的否定前缀；因为此词形成于古法语，我们可以说non-，来自 拉丁语 non- 在古法语中的衍生词。 第二个组成部分chalant， 是动词 chaloir 的古法语现在分词， 意思是.担忧的，关心的.。此词同样也来自于拉丁词calere ， 从其具体的感觉.热的或暖和的.演变到比喻的感觉.被激起或引起希望、热心或愤怒.。很明显古法语动词chaloir 已去掉了一些拉丁语 calere 的温暖， 不过，冷漠的人确是几乎没有什么热心或关心的。词语nonchalant 在734年前第一次被记录在英语中， 尽管法语nonchalence, 是法语 nonchalant 的派生词似乎已首先进入英语。 英语中的nonchalance 于'78年第一次被记录下来
