Millions of people all over the world use the word OK. In fact, some people say the word is used more often than any other word in the world. OK means all right or acceptable. It expresses agreement or approval. Some people say it came from the Native American Indian tribe known as the Choctaw(乔克托语). The Choctaw word “okeh” means the same as the American word okay. Experts say early explorers in the American West spoke the Choctaw language in the nineteenth century.
But many people doubt this. Language expert Allen Walker Read wrote about the word “OK” in reports published in the 1960s. He said the word began being used in the 1830s. Some foreign-born people wrote “all correct” as “o-l-l-k-o-r-r-e-c-t”, and used the letters OK. Other people say a railroad worker named Obadiah Kelly invented the word long ago. They said he put the first letters of his name--O and K--on each object people gave him to send on the train.
The organization supported Martin Van Buren for president in 1840. They called their group the OK club. The letters were taken from the name of the town where Martin was born--Old Kinderhook, New York.
Then there is the expression A-OK. It is a space-age expression. It was used in 1961 during the flight of astronaut Alan Shepard. He was the first American to be launched into space. His flight ended when his spacecraft landed in the ocean, as planned. Shepard reported, “Everything is A-OK.” One story says it was first used during the early days of the telephone to tell an operator that a message had been received.
There are also funny ways to say okay. These expressions were first used in the 1930s. Today, a character on the American television series “The Simpsons” says it another way. He says okely-doke.
| A．Some people say okey-dokey or okey-doke. |
