OK. WHY THIS BOOK? STRANGELY ENOUGH, EVEN THOUGH OK is by far the most successful American creation in language, as well as nearly the strangest, it hasn't had a book of its own. So here it is.
This is a book about OK. And OK truly deserves a book of its own, not only because it is different from anything else in our language but because it is so important. OK is a meme that has burrowed deeply into the way we think and act. In fact, those two letters encapsulate a whole view of life—the American philosophy, if two letters can be said to embody a philosophy, and if Americans can be said to have one.
