The word OK is an abbreviation of ‘orl korrect’. It was coined in the USA and means ‘all correct’. The word was first used as a slogan during the presidential re-election campaign of Martin Van Buren (1782–1862) in 1840. Van Buren’s nickname was “Old Kinderhook”. Back then, in Boston and New York abbreviations were the rage and words were misspelled deliberately. So a group of his followers called themselves the “O.K. Club”; this later went on to mean “oll korrect” and “Old Kinderhook”.
