On-air challenge: Every answer this week is a nine-letter phrase that's a palindrome — in other words, it reads the same both forward and backward.
For example: Certain floor models (4,5) --> some demos.
Last week's challenge, from listener Sandy Stevens of Bandon, Ore.: What one-syllable word in seven letters becomes a four-syllable word by inserting the consecutive letters I-T somewhere inside?
Answer: reigned, reignited.
Winner: Dan Bradshaw of Farmington, Conn.
Next week's challenge, from listener Norm Baird of Toledo, Wash.: If you squish the small letters "r" and "n" too closely together, they look like an "m." Think of a common five-letter word with the consecutive letters "r" and "n" that becomes its own opposite if you change them to an "m."
