Here's the latest from Will Shortz (NY Times' x-word puzzle editor), who offers a puzzle every Sunday on NPR's Weekend Edition:



Take the letters of the word TEMPORARY. Arrange them
in a 3 by 3 square so that each of the acrosses, downs and
the two long diagonals spells a word. Each of the diagonals
must read backward as well as forward, making 10 words to be
spelled altogether. All the words are common and
uncapitalized. What is this special square?
