雖然人們一星期都要使用這個詞達上百次來表示事情狀況的行或不行，但可能很少有人去探究這個詞的歷史。實際上，這個詞的歷史並不長，它第一次被記錄是在1839年，但毫無疑問這個詞在此之前就流通使用了。對於OK 這個詞的出處，已進行了很多研究， 其中艾倫·沃克·里德最終證實：OK 是出自一個笑話。有人把all correct這個詞組發音成 oll （或 orl ) correct， 這個人或別人又把它拼寫成oll korrect， 最後縮略成OK。這一名詞術語被1840年的來自紐約州金德胡克的民主黨總統候選人馬丁·凡·布倫作為政治宣傳口號。他出生於紐約的老金德胡克（OldKinderhoek），用這個地名的頭兩個字母作為競選口號，意思是“競選成功”。同時也使OK名聲大振。同年有一篇社論，對於收到帶有OK 口號的飾針之事作了以下評論：“可怕的字母，不僅對於說明馬丁·凡·布ok(9張)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召力的政治宣傳口號，‘一切正確’…那些別著這些飾針的人還應該心中有數要想把一切事都辦得令人滿意得需要他們長期不懈的努力”美國人對某件事表示贊同或認可時，常說ok，意思是好,行，不錯.這個用語，最初是美國鐵路扳道工人的用語。他們當班時，如果鐵路上一切正常，就說聲All correct，即完全正常。由於All音接近O,correct音近K,為了方便，工人們就省讀OK來表示同樣的意思。後來，詞義不斷演變，現在不但表示好,行，不錯這些意思，還包含有對別人的意見表示贊同，承認的意義。在簽名中也用於表示同意，認可。
值得提出的是，中國改革開放以來，OK一詞十分流行，成了時尚用語。但由於用得太濫，以至出現不少誤用現象。例如：美國同事高呼OK，向這位33歲的中國科學家表示祝賀。(《中華兒女》1992年第5期)斯束負爾先生蹲在地上看著中國螞蟻如此悲壯的舉動，像觀看一場世界級的足球比賽，嘴裡不停地驚嘆著：“OK! OK!”(《當代》1991年第1期)上面第一句的“OK”應改為“Congratulations”；第二句的“OK”應改為“Oh”或“God”。甚至還出現超出漢語規範的亂用。例如：評選的結果是李大鵬寫的“西安喜來登大酒店”最“OK”。(《中華兒女》1991年第3期)我所認識的邱昶，是熱情、忙碌、笑意盎然且很能OK的年輕人。(《羊城晚報》1994年7月24日)上面第一句的“OK”應改為漢字“好”；第二句的“OK”應改為為漢字“乾”。周海中教授在1995年發表的《關於“OK”》一文中認為，這種亂用“OK”的現象應該引起語言學界乃至全社會的高度重視。他在文中建議，中文報刊圖書中,最好將“OK”的含義用漢字書寫；如果喜歡使用“OK”以顯洋氣時，應持慎重態度，做到正確、規範，以免出洋相。
