<注釋>One might think that a word likefraction as well as its ancestors might have always referred to the mathematical fraction. 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 participlefr3ctus is derived Late Latin fr3ctiô, .a breaking. or .a breaking in pieces,.as in the breaking of the Eucharistic Host.In Medieval Latin the wordfr3ctiô 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 400.One of the next recorded instances of the word recalls its origins, referring to the .brekying or fraccioun. of a bone.
人們也許認(rèn)為一個(gè)詞如fraction 以及它的詞源總是指數(shù)學(xué)上的分?jǐn)?shù)。 當(dāng)然，分?jǐn)?shù)的數(shù)學(xué)概念也許早在公元前 2000年就已被巴比倫人所熟知。 但fraction 一詞僅能追溯到拉丁詞 frangere ，.打碎.。 源自過(guò)去分詞fractus 的詞干是派生的后期拉丁語(yǔ) fractio ， 意為.破裂.或.碎成一片片的.，如感恩節(jié)的餅的碎塊。在中世紀(jì)拉丁語(yǔ)中，fractio 一詞出現(xiàn)了數(shù)學(xué)意義， 這個(gè)詞連同此意義都被記入中世紀(jì)英語(yǔ)中。這個(gè)詞最早記載的意義是.一個(gè)數(shù)學(xué)單元，繁分?jǐn)?shù)或再分?jǐn)?shù)的約數(shù).，出現(xiàn)在約400年喬臾寫(xiě)的一部作品里。后來(lái)此詞有記錄的例子之一，指骨頭上的.裂痕或碎片.，使人回憶起它的起源
