<注釋>Words have changes in their fortunes over time just as people and institutions do.The wordnaughty at one time might have been high on one`s list as an all-purpose word similar to bad or nice. During the 'th centuryone could usenaughty to mean .unhealthy, unpleasant, bad (with respect to weather), vicious (of an animal), inferior, or bad in quality. (one could say .very naughtie figes. or .naughty corrupt water.). All of these senses have disappeared, however,andnaughty is now used mainly in contexts involving mischief or indecency. This recalls its early days in Middle English (with the formnoughti ), when the word was restricted to the senses .evil, hostile, ineffectual, and needy..Middle Englishnoughti, first recorded in works written in the last quarter of the 4th century, was derived fromnought, which as a noun had senses such as .evil,.as a pronoun meant .nothing,.and as an adjective could mean such things as .immoral, weak, useless..Nought was descended from Old English n3wiht, with similar senses,a compound made up ofn3, .no,. and wiht, .thing, being.. Thusnaughty, in a sense, has risen from nothing,but its fortunes have been better than they are at present.
正像人們和制度那樣，詞隨著時(shí)間改變了意思。單詞naughty 曾一度作為類似于 bad 或 nice 這種通用詞語而列于某人的詞匯表中。 在'世紀(jì)，人們可以用naughty 來指.不健康的，不舒服的，壞的（和天氣相關(guān)的），邪惡的（動物），較劣的，或質(zhì)量壞的.（人們可以說.非常壞的人. 或.不健康的被污染的水.）。 然而所有的這些詞義都消失了，現(xiàn)在naughty 主要用于關(guān)系到頑皮或不妥的上下文中。 這使人回想起它在中世紀(jì)英語的早些時(shí)候形式為naughti ， 當(dāng)這個(gè)詞被限定為用作.邪惡的，敵意的，無用的，和貧窮的.意思。中世紀(jì)英語的noughti 最先記錄于寫于4世紀(jì)后二十五年的著作中， 是由nought 派生而來的， 作為名詞用有.邪惡.的意思，作為代詞用是.沒有.的意思，和作為形容詞為.不道德的，虛弱的，無用的.。Nought 是從古英語 nawiht 中傳下來的， 并且有相似的意思，由na .沒有.和 wiht .事情，事物.組成的合成詞。 這樣naughty 從某種意義上來說， 從沒有中生出，但是其意思卻比現(xiàn)在的這些意思好得多
