Puzzle master Will Shortz quizzes one of our listeners, and has a challenge for everyone at home.
Challenge from April 30: From Merl Reagle: Take the word formaldehyde. Rearrange its 12 letters to spell two shorter words that are uncapitalized and very common. Each one has just one syllable. Not counting a slight variation, we think the answer is unique. What words are they?
Answer: Rhymed and foaled or rhymed and loafed.
Winner: Derek Teare of Grantham, New Hampshire.
Challenge from May 7: From Mike Reiss of Los Angeles. Take two words that go together to make a familiar phrase in this form: "blank and blank." Both words are plurals, such as "bells and whistles." Move the first letter of the second word to the start of the first word. You'll get two new words that name forms of transportation. What are they?
