Arrange the letters A, A, B, E, N, P, R, U and Y into a 3x3 grid so that the three rows read left-to-right as three common words, as do the three columns from top to bottom, and the two diagonals also from top to bottom.
The only solution is:
P U B
E R A
A N Y
The 3 rows provide the words: PUB, ERA and ANY
The 3 columns provide the words: PEA, URN and BAY
The two top-bottom main diagonals provide the words: PRY and BRA.
