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. You might ask your brother, "Is it okay if I borrow your car?” Or if someone asks you to do something, you might say, “Okay, I will.” Still, language experts do not agree about where the word came from.
Some people say it came from the Native American Indian tribe known as the Choctaw. 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. The language spread across the country.
But many people dispute this. Language expert Allen Walker Read wrote about the word OK in reports published in the nineteen sixties. He said the word began being used in the eighteen thirties. It was a short way of writing a different spelling of the words “all correct.” Some foreign-born people wrote “all correct” as “o-l-l k-o-r-r-e-c-t,” and used the letters O.K.
Other people say a railroad worker named Obadiah Kelly invented the word long ago. They said he put the first letters of his names -- O and K -- on each object people gave him to send on the train.
Still others say a political organization invented the word. The organization supported Martin Van Buren for president in eighteen forty. They called their group, the O.K. Club. The letters were taken from the name of the town where Martin Van Buren was born — Old Kinderhook, New York.
Not everyone agrees with this explanation, either. But experts do agree that the word is purely American. And it has spread to almost every country on Earth.
