Afraid you may be losing your perspicacity*? An opportunity to test yourself is just hours away. But what if the questions come from a guy who, according to an article in the New York Times, “has a tattoo of the phonetic vowel chart on his back”? Steve Kleinedler, owner of the aforementioned tattoo, will be presenting a Define-a-thon at the Ann Arbor Book Festival on Saturday, May 19. According to the article, Define-a-thons, sponsored by Houghton Mifflin’s American Heritage Dictionaries, are sweeping the nation, and attracting huge crowds to witness contestants battling for largest lexicon. I, for one, am relieved not to be competing—I had to keep dictionary.com open while reading the article—tintinnabulation, anyone?
