Thank you all for the discussion and explanations.
Jim, if you are not familiar with the RTE Guide crossword, my advice would be - DON"T become acquainted. It is a truly masochistic tendency that makes me try it, but it is the worst excuse for a crossword I have ever seen. I don't equate crosswords with puzzles. The RTE Guide is a mixture of crossword and puzzle. The clues can be squiggly lines, circles, arrows etc. It has had anagrams misspelt, anagrams with letters missing. I want to know how much Rosebud gets paid for this rubbish.
