0/10. You destroyed me! I might on a good day have got two groups but the others although obvious when you see the answers would have beaten me on my very best day. In the very best tradition of the original and I tip my hat to you for a supremely difficult (but not unsolvable) quiz.

What Moondog said!

Thanks ;-) it probably needed a group that wasn't a word prefix or suffix one (other than the false trails). Once you see the potential for herring though it is hard to unsee.
