AS an avid Sudoku doer I regularly look at the Word Wheel when I am stuck as a form of respite. Though reasonably successful at getting the nine-letter word, I have been baffled by some. I have always prided myself in having a reasonable vocabulary but given some of the obscure words used I guess I must take yesterday's solution (for April 12) to heart and lucubrate even harder (yes, I did have to consult the dictionary).
