May I ask the origin of English slang Okeydoke?

The word comes from Orrin Kendall (abbreviated as OK), a businessman who made cookies during the Civil War more than 0/00 years ago. His products are very popular in the wholesale army, and every biscuit is printed with the letter OK as a trademark.

Jackson, the seventh president of the United States, served as a court document in his early years. After each record was checked correctly, he approved the word OK, which means Oll Korrect. Later, when Jackson was running for president, some people on the other side used this legend to slander him, saying that he was an uneducated person and wrote something else.

The word Okay was invented by a political group in the19th century. A man named Martin Van Buren will run for president. His supporters set up a club to promote him. The name of the club is "Okay Club". It is said that the letters O and K are taken from Van Buren's hometown and his birthplace, Old Kinderhook, new york.

Extended data:

OK is an informal spoken word. It means: OK, that's acceptable. You can also agree, 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.

When Americans express their approval or recognition of something, they often say ok, which means "good", "good" and "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 All sound is close to "O" and the correct sound is close to "K", for convenience, workers omit reading "OK" to mean the same thing. Later, the meaning of words has been constantly evolving, and now it not only refers to "good", "not bad" and "not bad", but also includes the meaning of agreeing with and acknowledging other people's opinions. It is also used for signing, expressing agreement and approval.
