導語：英語詞根一般決定單詞的性質，或是基本意思，下面是表示“新”的英語詞根——nov的介紹，歡迎參考！
英語單詞裏面出現nov的時候，一般表示“新”，例如：
novel adj. 新奇的；
renovate vt. 更新，修復；
novice n. 初學者，新手；
innovation n. 創新，革新；
supernova n. [天] 超新星；
①novice
(1) One who has no previous training or experience in a specific field or activity; beginner.
(2) A new member of a religious order who is preparing to become a nun or monk.
It's hard to believe that a year ago she was a complete novice as a gardener, who couldn't identify a cornstalk.
Among the ancient Romans, a novice (novicius) was usually a newly imported slave, who had to be trained in his or her duties. Among Catholics and Buddhists, if you desire to become a priest, monk, or nun, you must serve as a novice for a period of time, often a year (called your novitiate), before being ordained or fully professing your vows. No matter what kind of novice you are—at computers, at writing, at politics, etc.—you've got a lot to learn.
在古羅馬時期， novice表示剛運過來、待訓練的的奴隸；在一些宗教體系裏面，novice表示成爲牧師、和尚或者修女之前要經歷的類似實習期的身份；在英語裏一般表示“新手”，類似的詞還有newbie，green hand等等。
②novel
(1) New and not resembling something formerly known or used.
(2) Original and striking, especially in conception or style.
His techniques for dealing with these disturbed young people were novel, and they caught the attention of the institute's director.
If someone tells you that you've come up with a novel idea or a novel interpretation of something, it's probably a compliment: not everyone is capable of original thinking. But not everything new is terribly worthwhile; a novelty, for example, is often a cute (or maybe just silly) little object that you might put on a display shelf in your house. It may seem surprising that the familiar noun novel is related as well. In the 14th century, Italian writers began writing collections of short tales, each of which they called a novella because it represented a new literary form; from this word, three centuries later, the English coined the noun novel.
十四世紀的時候，意大利作家開始寫一些短的傳說故事，他們起名叫novella，因爲這些短故事代表一種新的文學形式，到了十七世紀的時候，英語裏就用novel表示“小說”了。U君提示大家，在小說裏面，fiction更強調虛構、科幻的故事；non-fiction 側重紀實文學；novel一般表示篇幅較長的.小說。
③innovation
(1) A new idea, device, or method.
(2) The introduction of new ideas, devices, or methods.
“Smooshing” bits of candy into ice cream while the customer watched was just one of his innovations that later got copied by chains of ice-cream outlets.
Innovation is a word that's almost always connected with business. In business today, it's almost a rule that a company that doesn't innovate is destined for failure. The most important and successful businesses were usually started by innovators. And company managers should always at least listen to the innovative ideas of their employees.
Creation和innovation都代表創新，但是creation表示從無到有的創造，而innovation側重對已有的東西進行革新。
④supernova
(1) The explosion of a star that causes it to become extremely bright.
(2) Something that explodes into prominence or popularity.
After exploding, a nova leaves a “white dwarf” which may explode again in the future, but a supernova destroys the entire star.
A nova, despite its name, isn't actually a “new” star, but rather one that wasn't noticed until it exploded, when it may increase in brightness by a million times before returning to its previous state a few days later. A supernova is far larger; a star in its supernova state may emit a billion times as much light as previously. After a few weeks it begins to dim, until it eventually ceases to exist; it's often replaced by a black hole. (Though remains that were shot out into space may survive; those of a great supernova seen in A.D. 1054 are now known as the Crab Nebula.) All this may serve as a warning to those human stars whose fame explodes too rapidly; supernovas of this kind have sometimes vanished by the following year.
超新星爆發是某些恆星在演化接近末期時經歷的一種劇烈爆炸。這種爆炸度極其明亮，過程中所突發電磁輻射經常能夠照亮其所在的整個星系，並可持續幾周至幾個月（一般最多是兩個月）纔會逐漸衰減變爲不可見。在這段期間內一顆超新星所輻射的能量可以與太陽在其一生中輻射能量的總和相媲美。2016年1月，中國科學家觀測到最強超新星，是太陽亮度5700億倍。
