<注釋>Although we use this word hundreds of times a week whether things are OK or not,we have probably rarely wondered about its history.That history is in fact a brief one,the word being first recorded in 839,though it was no doubt in circulation before then.Much scholarship has been expended on the origins ofOK, but Allen Walker Read has conclusively proved thatOK is based on a sort of joke. Someone pronounced the phraseall correct as oll (or orl ) correct, and the same person or someone else spelled itoll korrect, which abbreviated gives usOK. This term gained wide currency by being used as a political slogan by the 840 Democratic candidate Martin Van Buren,who was nicknamedOld Kinderhook because he was born in Kinderhook, New York.An editorial of the same year,referring to the receipt of a pin with the sloganO.K., had this comment: .frightful letters . . . significant of the birth-place of Martin Van Buren, old Kinderhook,as also the rallying word of the Democracy of the late election,‘a(chǎn)ll correct’ . . . Those who wear them should bear in mind that it will require their most strenuous exertions . . . to make all things O.K..
雖然我們一星期都要使用這個(gè)詞達(dá)上百次來(lái)表示事情狀況的行或不行，但我們可能很少有人去探究這個(gè)詞的歷史。實(shí)際上，這個(gè)詞的歷史并不長(zhǎng)，它第一次被記錄是在839年，但毫無(wú)疑問(wèn)這個(gè)詞在此之前就流通使用了。對(duì)于OK 這個(gè)詞的出處，已進(jìn)行了很多研究， 但艾倫·沃克·里德最終證實(shí)OK 是出自一個(gè)什么笑話。 有人把all correct 這個(gè)詞組發(fā)音成 oll （或 orl ) correct， 這個(gè)人或別人又把它拼寫成oll korrect， 最后縮略成OK 。 這一名詞術(shù)語(yǔ)被804年的民主黨總統(tǒng)候選人馬丁·凡·布倫作為政治宣傳口號(hào)而得到廣泛運(yùn)用。馬丁的綽號(hào)是老金德胡克 ， 因?yàn)樗錾诩~約州的金德胡克。同年有一篇社論，對(duì)于收到帶有OK 口號(hào)的飾針之事作了以下評(píng)論： .可怕的字母，不僅對(duì)于說(shuō)明馬丁·凡·布倫的出生地紐約州的金德胡克很重要，而且它還是近期所舉行大選的民主黨的頗具號(hào)召力的政治宣傳口號(hào)， .一切正確.…那些別著這些飾針的人還應(yīng)該心中有數(shù)要想把一切事都辦得令人滿意得需要他們長(zhǎng)期不懈的努力.
