''OK'' is perhaps the most recognized word worldwide. It originated in the 1830s from a fad of misspelling abbreviations among young intellectuals in Boston, where "OK" stood for "oll korrect."
Its popularity grew after being published in the Boston Morning Post in 1839 and further cemented during Martin Van Buren’s 1840 presidential campaign. The word's adoption was propelled by the telegraph, as it was easy to transmit and confirm messages.
OK’s visual appeal, particularly the rare use of the letter 'K,' also contributed to its widespread usage. Despite debates and myths about its origin, "OK" has become embedded in the English language as a neutral affirmative, widely used without emotional connotation. It even made history by being one of the first words spoken on the moon.
