Q. Why write a whole book about OK? I mean, it’s just…OK.
A. Ah, but it’s OK the Great: the most successful and influential word ever invented in America. It’s our most important export to languages around the world—best known and most used, though used sometimes in weird ways. It expresses the pragmatic American outlook on life, the American philosophy if you will, in two letters. And in the twenty-first century, inspired by the 1967 book title I’m OK, You’re OK (which is the only famous quotation involving OK), it also has taught us to be tolerant of those who are different from us. On top of all that, its origin almost defies belief (it was a joke misspelling of “all correct”) and its survival after that inauspicious origin was miraculous. And strangely, though we use it all the time, we carefully avoid it when we’re making important documents and speeches. So, wouldn’t you say OK deserves a book?
