OK
An English expression meaning approval or acceptability; it spread from nineteenth-century America and is now borrowed directly into many languages.
"OK" began as a newspaper joke in 1839 Boston. Educated young people then had a fad of deliberately misspelling abbreviations, so "all correct" became "oll korrect," shortened to "o.k." It spread nationwide the next year as short for "Old Kinderhook," the nickname of candidate Martin Van Buren.
