Allan Metcalf"s new book claims that the word "OK" is America"s greatest invention. This offers a pair of provocations. How can "OK" be an invention On a certain day, a certain guy just dreamed up the expression that has become the most frequently spoken word on the planet And even if it is an invention, can one little word really be greater than jazz, baseball, and the telephone Is it better thanThe SimpsonsThe answer to the first question, implausible as it sounds, is yes. In OK:The Improbable Story of America"s GreatestWord, Metcalf locates the first use of OK in an obscure corner of a Boston newspaper on March 23, 1839. As for the alleged greatness of the word, Metcalf"s slim volume doesn"t entirely persuade you that OK is a more valuable invention than, say, electric light. But the fact that he even raises the question is intriguing. If it does nothing else, Metcalf makes you acutely aware of how universal and vital the word has become.True story: the world"s most popular word began as a joke. In the late 1830s, America"s newspapers had great enthusiasm for abbreviations—also, to judge by Metcalf"s account, a sorry sense of humor. He devotes a chapter to trying to explain why readers of the Boston Morning Post might have been amused to see "o. k." used as a jokey abbreviation for "oll korrect," an intentional misspelling of "all correct." Apparently you had to be there. But the word soon got an enormous boost from Andrew Jackson—or his enemies, anyway. They circulated the rumor that the man of the people was barely literate and approved papers with the initials "O. K." for "oll korrect." It was a joke, Metcalf concludes, "but without it there"d be no OK."The word didn"t remain a joke for long. Telegraph operators began using it as a way to say "all clear." It became ubiquitous, turning up in all comers of the world, and beyond. Metcalf points out that OK was technically the first word spoken on the surface of the moon.When you pause to consider what a weird and wonderful little word OK is, the most remarkable thing isn"t that it"s so great or that it was invented but that it"s American. To foreigners in the 20th century, Metcalf writes, the word embodied "American simplicity, pragmatism, and optimism." To us today, the word sums up "a whole two-letter American philosophy of tolerance, even admiration for difference." Which of the following is true about Andrew Jackson
A. He was the inventor of "OK".
B. He was poor in writing and reading.
C. He was a household name in America.
D. He was the editor of the Boston Morning Post.
