OK, 'most spoken word on the planet', marks its 175th anniversary
It will be 175 years since OK - or, as some prefer, okay - first appeared in print, on page two of The Boston Morning Post, then one of the most popular newspapers in the United States.
Whatever you're doing today, wherever you might be, take a moment to reflect on the most popular word in the English language, OK?
It will be 175 years since OK - or, as some prefer, okay - first appeared in print, on page two of The Boston Morning Post, then one of the most popular newspapers in the United States.
"I think OK should be celebrated with parades and speeches," Allan Metcalf, an English professor in Illinois who is the world's leading authority on the history and meaning of OK, said.
"But for now, whatever you do [to mark the anniversary], it's OK."
In his 2001 book, OK: The Improbable Story of America's Greatest Word, Metcalf calls OK "the most frequently spoken (or typed) word on the planet".
Concise and utilitarian, it's quintessentially American in its simplicity. Etymologically, it has no direct relationship with Latin or Greek or any other ancient tongue.
Oxford Dictionaries, on its website, rejects speculation that OK is derived from the Scottish expression "och aye," the Greek "ola kala" (it's good) or the French "aux Cayes," which refers to a Haitian port famous for its rum.
