A Burlington, Vt. caller wants to know: Is horseradish so named because of this root’s strong resemblance to part of a horse’s anatomy?

The word zarf means “a metal cupholder,” but a Scrabble enthusiast says other players always challenge his use of that word. He wants to know its origin.

What word in the English language is an anagram of itself? Hint: It’s a trick question.

Puzzle Dude John Chaneski has a quiz about the unofficial terms for familiar things that have less familiar official names. “The Academy Awards of the American Academy of Motion Picture Arts and Sciences,” for example, are unofficially called the Oscars.

An Orange County, California, listener describes how both his left-handed parents were forced as children to learn to write with their non-dominant hand.

The story behind the word ignoramus is big fun. It involves a bumbling lawyer, a six-hour farce from the 17th century, and a Latin legal term. See? Big fun.

If you need proof that language is powerful, here’s some. Researchers at Cornell recently reported that kids are more likely to eat their veggies if they’re told the food has enticing names like “X-ray Vision Carrots” and “Dinosaur Broccoli Trees.” Wonder how big a grant the researchers got to study what every parent already knows.

Did you learn the vowels as “a,” “e,” “i,” “o” “u,” and sometimes “y” and “w”? A caller who was taught that in second grade was left wondering: When and where does “w” function as a vowel?
