Word origin

The origin is genuinely disputed, though both leading accounts point to the United States around 1839 to 1840.

Other proposed origins

Most scholars trace it to a Boston newspaper joke of 1839 that spelled all correct as oll korrect and shortened it to OK. (American English, oll korrect)
Others credit the 1840 campaign of Martin Van Buren, whose supporters formed the OK Club after his nickname Old Kinderhook. (American English, Old Kinderhook)
