Toen mijn vrouw en ik twee jaar geleden in Seattle WA waren, vonden wij in een tijdschrift deze toelichting op O.K.:“Everybody uses these two letters. Sometimes we make them into the word okay. Although American in origin, the whole world knows the meaning. The two letters were first used by the Democratie O.K. Club back in 1840. Martin Van Buren, who was president of the United States at that time, was born in Kinderhook, a village in New York state. So people gave him the nickname 'Old Kinderhook'. The name became popular when he was seeking a second term. His friends thought he had done well as president and endorsed him for another four years in office. So the letters O.K. came to mean 'all right', 'correct', 'approval'.
