I often use OK as a short cut. I have never known what the letters ‘O’ and ‘K’ in OK stand for so I decided to do a litle research. I found dozens of suggestions.
The most likely explanation is that the term originated as an abbreviation of orl korrekt , a jokey misspelling of ‘all correct’ which was current in the US in the 1830s. The oldest written references result from its use as a slogan by the Democratic party during the American Presidential election of 1840. Their candidate, President Martin Van Buren, was nicknamed ‘Old Kinderhook’ (after his birthplace in New York State), and his supporters formed the ‘OK Club’. This undoubtedly helped to popularize the term (though it did not get President Van Buren re-elected).
I’m not completely satisfied as yet, but I am at least a little wiser. How about you…..OK?
