OK is an informal spoken word. It means: not bad, acceptable, not too bad and not too good. You can also agree. OK can also be written as OK or O.K, with the same pronunciation. It is also the most famous English word in the world! Although we use this word hundreds of times a week to indicate whether things are going well or not, few of us will explore the history of this word. In fact, the history of this word is not long. It was first recorded in 1839, but there is no doubt that this word has been used in circulation before this. There have been many studies on the origin of the word OK, but alan walker Reid finally proved that OK is a joke. Someone pronounced the phrase all correct as oll (or orl) correct, this person or others spelled it as oll korrect, and finally abbreviated it as OK. This word was widely used as a political propaganda slogan by Democratic presidential candidate Martin Van Buren from 65438 to 0804. Martin's nickname is Old Kinderhook, because he was born in Kinderhook, new york. In the same year, an editorial commented on the pin with the OK slogan: "This terrible letter is not only important to explain Martin Van Buren's birthplace in Kinderhook, New York, but also an attractive political propaganda slogan for the Democratic Party which recently held a general election." Everything is right "... people who wear these pins should also know that it takes them long-term unremitting efforts to make everything satisfactory. When Americans agree or approve something, they often say ok, which means "good", "ok" and "very good". This term was originally used by American railway switchmen. When they are on duty, if everything is normal on the railway, they say that everything is correct, which means "completely normal". Because the sound of All is close to "O", and the correct sound of O is close to "K", for convenience, workers omit reading "OK" to express the same meaning. Later, the meaning of words has been constantly evolving. Now it not only means "good", "good" and "not bad", but also means agreeing with and acknowledging other people's opinions. It is also used to express agreement and recognition in a signature.
