The Top Ten Word List for 2003 from yourDictionary.com...

Here's something I learned:

Most frequently spoken word on the Planet:
1. OK Still the most popular word in languages around the world. "OK" originated in a joke in the 1830's, spelled "oll korrekt" in Boston newspapers, the joke being, both words were incorrect. It became so popular, that it was soon abbreviated to simply "O. K." Despite its popularity, the word would have fallen by the wayside had not Martin van Buren, called "Old Kinderhook" for being born in Kinderhook, N.Y. used it in his presidential reelection campaign of 1840. So don't "misunderestimate" the impact of presidential usage on the growth of our vocabulary. It is also spelled "okay."
