Truthiness. Stephen Colbert continues his War on the AP.

The Oxford English Dictionary has a definition for "truthy" dating back to the 1800s. It's defined as "characterized by truth" and includes the derivation "truthiness."

Michael Adams, a visiting associate professor at North Carolina State University who specializes in lexicology, pointed to that definition and has said Colbert's claim to inventing the word is "untrue." (Adams served as the expert opinion in the initial AP story.)

"The fact that they looked it up in a book just shows that they don't get the idea of truthiness at all," Colbert said Thursday. "You don't look up truthiness in a book, you look it up in your gut."
