📜 OK Day History

What is known is that the term “OK” first appeared when a clever editor from the Boston Morning Post deliberately misspelled “all correct” as “all korrect” as a sarcastic jab at his counterpart. Surprisingly, this slang term became part of everyday American language, although it had not yet gained widespread popularity at that time.

Many people mistakenly believe that “OK” originated from a political slogan, mainly because we currently live in a historical period where this is the case. In 1840, presidential candidate Martin Van Buren used the phrase “Vote for OK,” which gained significant attention. However, the “OK” in this context referred to Van Buren’s nickname, “Old Kinderhook,” related to his hometown. His opponents, the Whigs, went further and spread false allegations that Van Buren used “OK” instead of “all correct” because he couldn’t spell, even claiming he signed documents that way. These allegations harmed Van Buren’s reelection campaign but inadvertently boosted the word’s popularity. As time passed, “OK” began to be used to signify correctness in signed papers and even telegrams, despite objections from notable writers. Nevertheless, the word’s growth was unstoppable, and it eventually gained global recognition.

An American etymologist named Allen Walker Read became fascinated by the word “OK” and thoroughly investigated its origins and various legends surrounding it. He concluded that the term originated from an 1839 article in the Boston Morning Post and published his findings in a series of essays from 1963 to 1964. Although there are ongoing debates about Read’s conclusions, one thing is certain: “OK” is firmly rooted in our language and widely accepted.
