Hello Khalid According to wikipedia: The historical record shows that O.K. appeared as an abbreviation for "oll korrect" (a conscious misspelling of "all correct") in Boston newspapers in 1839, and was reinterpreted as "Old Kinderhook" in the 1840 United States presidential election. Because it is a recent word born of word play, and because it is so widely used, O.K. has also invited many folk etymologies. These competing theories are not supported by the historical written record, except in that folk and joke etymologies influenced the true history of the word. Since the 19th century, the word has spread around the world, the okay spelling of it first appearing in British writing in the 1860s. Spelled out in full in the 20th century, 'okay' has come to be in everyday use among English speakers, and borrowed by non-English speakers.

Oll korrect This is historically the most interesting etymology, based on Read's extensive discussion of it, and it became widely known following his landmark publications in 1963-1964. Allen Walker Read, revisiting and refuting his own work of 20 years earlier, contributed a major survey of the early history of okay in a series of six articles in the journal American Speech in 1963 and 1964 He tracked the spread and evolution of the word in American newspapers and other written documents, and later the rest of the world. He also documented controversy surrounding okay and the history of its folk etymologies, both of which are intertwined with the history of the word itself. A key observation is that, at the time of its first appearance in print, a broader fad existed in the United States of "comical misspellings" and of forming and employing acronyms and initialisms. These were apparently based on direct phonetic representation of (some) people's colloquial speech patterns. Examples at the time included K.Y. for "know yuse" and N.C. for "'nuff ced".[14] "The abbreviation fad began in Boston in the summer of 1838 ... OFM, "our first men," and used expressions like NG, "no go," GT, "gone to Texas," and SP, "small potatoes." Many of the abbreviated expressions were exaggerated misspellings, a stock in trade of the humorists of the day. One predecessor of okay was OW, "oll wright," and there was also KY, "know yuse," KG, "know go," and NS, "nuff said."[15] The general fad may have existed in spoken or informal written U.S. English for a decade or more before its appearance in newspapers. OK's original presentation as "all correct" was later varied with spellings such as "Oll Korrect" or even "Ole Kurreck". Deliberate word play was associated with the acronym fad and was a yet broader contemporary American fad. The chief strength of this etymology is its clear written record. i hope this give you idea cowboy...

Various etymologies have been proposed for okay, but none has been unanimously agreed upon. Most are generally regarded to be unlikely or anachronistic. There are five proposed etymologies which have received material academic support since the 1960s. They are: Greek words "Ola Kala" meaning "everything's good" or "all good" used by Greek railroad workers in the United States. It is possible that Greek sailors used Ola Kala in American ports. It is also said that "O.K." was written on the ships or other places to show that the ships are ready. Acronym of the "comically misspelled" oll korrect Acronym of "Old Kinderhook" Choctaw word okeh Wolof and Bantu word waw-kay or the Mande (aka "Mandinke" or "Mandingo") phrase o ke The "comically misspelled" one has been extensively discussed by Allen Walker Read although the purpose of those discussions was to promote "Old Kinderhook"; the last two differ materially from other candidates in that they: Have widespread verifiable pre-existing documented usage, Have verifiable geographic overlaps with okay's first documented instances, Have equivalent meanings, Do not fit over-neatly into contemporaneous or subsequent political or cultural circumstances, and Are remarkably similar in pronunciation to okay (having due regard to the danger of false coincidence, which is endemic to colloquial etymology) cowboy...

Adams, a linguist and a College professor says there are words like OK in many other languages. In the West African language of Wolof, "waw kay" means "yes." In Choctaw, "okeh" means "indeed." While there isn't any proof that any of the words gave birth to the American OK, Adams says it's possible that the many non-English phrases helped the English one stick. Some believe it came from the abbreviation of Orrin Kendall biscuits, which soldiers ate during the civil war. Others say OK is short for Aux Cayes, a Haitian port that American sailors praised for its rum. Another legend suggests the word comes from Old Keokuk, a Native American tribal chief who was said to have signed treaties with his initials. But none of those versions have been proven correct!

Hello Khalid , It is one of the unanswerable linguistic questions . In fact no one knows for sure. Some stories surrounding the word OK: * The Greeks had an incantation of "Omega, Khi" with which they drove away fleas. * The Finnish language has the word "oikea." * Liberian English has the term "oke." * Burmese has "hoakeh." * The infamous jokers at the Boston Morning Post claimed, in 1839, OK was short for "ORL KORREKT." * The Times, in 1939, claimed it had London Cockney origins, from "Orl Korrec." * American Indians used the word "okeh" which meant "it is so." The story goes that Andrew Jackson picked up the word during the Battle of New Orleans in 1815. * Some Latin scholars claim that "Omnis Korecta" is the origin.
