“OK” originated in 1830s America as a joke abbreviation for the misspelled phrase “oll korrect.” It gained national attention during Martin Van Buren’s 1840 presidential campaign and eventually became one of the most widely used words in the world.
One of the world’s most common words started as a joke. In 1839, Boston newspapers popularized a trend of humorous misspelled abbreviations, and “OK” emerged from “oll korrect,” a playful spelling of “all correct.” While most of these expressions quickly faded, OK endured.
Its popularity grew further during the 1840 presidential campaign of Martin Van Buren, whose supporters formed “OK Clubs” that referenced both the abbreviation and his nickname, “Old Kinderhook,” taken from his hometown in New York. Today, OK is recognized around the globe and remains one of the most universally understood words in any language.
