Q: Create a 4-by-4 crossword square with four four-letter words reading across and four different four-letter words reading down. Use the word 'nags' at 1 across and the word 'newt' at 1 down. All eight words must be common, uncapitalized words, and all 16 letters must be different.You could use recent hints in my other post...
Edit: My hint last week was "a tan" which coincidentally works this week as a clue to the least common word in the grid. I'd put ecru in the same family as tan, beige and khaki. In addition, reading the first letter of each word in my clue (Y,C,U,R,H,I,M,O,P) gives you the set of letters needed to complete the crossword square.
A:Across: NAGS, ECRU, WHIM, TYPO
Down: NEWT, ACHY, GRIP, SUMO
