How did "ok" came about? Who invented it and what's the origin?

Answer 1

I got this from www.dictionary.com:

OK is a quintessentially American term that has spread from English to many other languages. Its origin was the subject of scholarly debate for many years until Allen Walker Read showed that OK is based on a joke of sorts. OK is first recorded in 1839 but was probably in circulation before that date. During the 1830s there was a humoristic fashion in Boston newspapers to reduce a phrase to initials and supply an explanation in parentheses. Sometimes the abbreviations were misspelled to add to the humor. OK was used in March 1839 as an abbreviation for all correct, the joke being that neither the O nor the K was correct. Originally spelled with periods, this term outlived most similar abbreviations owing to its use in President Martin Van Buren's 1840 campaign for reelection. Because he was born in Kinderhook, New York, Van Buren was nicknamed Old Kinderhook, and the abbreviation proved eminently suitable for political slogans. That same year, an editorial referring to the receipt of a pin with the slogan O.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, ‘all correct’.... Those who wear them should bear in mind that it will require their most strenuous exertions... to make all things O.K.”

Answer 2

In the Choctaw language, there is a word "okeh" with the same meaning and pronunciation as American usage; Woodrow Wilson, among others, used this spelling to emphasize the Native American origins of the word. The Choctaw language was well known as a lingua franca of the frontiersmen of the early 19th Century, including eventual American Presidents Andrew Jackson and William Henry Harrison.

Answer 3

There are several theories about the origins of this word, some of them apocryphal and none of them conclusive, although the suggested origin as an initialism of oll korrect has relatively widespread support.

Allen Walker Read believed the word to be short for any of several different spellings of "all correct", including "Oll Korrect", "Orl Korrect", and "Ole Kurreck". There was a fad in the 1830s and 1840s involving the intentional misspelling of common phrases, and referring to them by the resulting initials.

Native american origin.

O.K. is facetious misspelling of "all correct" "oll korrect"
