Certainly the mathematical notion of a fraction was known to the Babylonians, perhaps as early as 2000b.c. But our wordfraction goes back only to the Latin word frangere, "to break.” From the stem of the past participlefrāctus is derived Late Latin frāctiō, "a breaking" or "a breaking in pieces,”as in the breaking of the Eucharistic Host.In Medieval Latin the wordfrāctiō developed its mathematical sense, which was taken into Middle English along with the word.The earliest recorded sense of our word is "an aliquot part of a unit, a fraction or subdivision,”found in a work by Chaucer written about 1400.One of the next recorded instances of the word recalls its origins, referring to the "brekying or fraccioun" of a bone.人们也许认为一个词如fraction 以及它的词源总是指数学上的分数。 当然，分数的数学概念也许早在公元前 2000年就已被巴比伦人所熟知。 但fraction 一词仅能追溯到拉丁词 frangere ，“打碎”。 源自过去分词fractus 的词干是派生的后期拉丁语 fractio ， 意为“破裂”或“碎成一片片的”，如感恩节的饼的碎块。在中世纪拉丁语中，fractio 一词出现了数学意义， 这个词连同此意义都被记入中世纪英语中。这个词最早记载的意义是“一个数学单元，繁分数或再分数的约数”，出现在约1400年乔臾写的一部作品里。后来此词有记录的例子之一，指骨头上的“裂痕或碎片”，使人回忆起它的起源〔ravel〕To say that we will ravel the history ofravel is an ambiguous statement, given that history. Ravel comes from the obsolete Dutch verbravelen, "to tangle, fray out, unweave,” which comes in turn from the nounravel, "a loose thread.” We can see the ambiguity ofravel already in the notion of a loose thread, because threads can be loose when they are tangled or when they are untangling.The Dutch verb has both notions present in it,denoting both tangling and unweaving.In one of its earliest recorded uses in English (before 1585)the verb means "to become entangled or confused,”and in 1598 we find a use in the sense "to entangle.”But in 1611 the word is used with reference to a fabricin the sense "to fray out,”and in 1607 in the sense "to unwind, unweave, or unravel.”In 1582 we already have an author using the word in a figurative way to mean "to take to pieces or disentangle,”while in a work written before 1656 we have a figurative instance of the sense "to entangle or confuse.”Clearly there was a need for the wordunravel, which is first found in 1603, but strangely enoughit did not solve the problem,ravel retaining up to this day both "entangling" and "disentangling" senses. 说我们要解开ravel 这个词的历史， 只要“历史”的意思不变，这种说法本来就是含糊的。 Ravel 这个词来源于意为“纠缠，磨损掉，解开”的废荷兰语动词ravelen， 而这个词又是从意为“一束松线”的名词ravel 衍生而来的。 在这个意思中，我们已经能看到ravel 的双重意思， 因为一团线缠起来或被解开后都有可能松散。荷兰语的这个词两个意思都有，既指缠起来又指松开。 (1585年前）这个词在英语中第一次使用时，它是“变得纠缠在一起、和含混不清”的意思，1598年我们又发现了“使缠在一起”的意思。但1611年当这个词用于指纺织品时，它却是“使散开”的意思，1607年它的意思是“倒转，松开，打开。”1582年有一位作家已经使用这个词的比喻义“散成一片片或分开”，而在一部写于1656年前的著作中，又有“缠紧，弄混”的比喻意义。毫无疑问，出现于1603年的unravel 这个词有必要的存在， 但非常奇怪的是,这并没有解决ravel 这个词直到现在还有“缠紧”和“分开”这两个意思 〔bench〕A level, narrow stretch of land interrupting a declivity.阶地，梯田：在斜坡上隔成的水平而狭窄的一片片土地 |
