Thanks Patsy. If Cur is right, and it probably is, I don't get how it links to canine tooth other than cur being a dog, but where does the "first part" fit in??
I didn't give the clues for 18D and 12A as I was sure of the answers. I did give you the clue for 22A and the answer to 19A.
Sorry if that wasn't enough but thanks for the explanations that I just couldn't see.
Thanks Robin. Maybe it would have been less confusing if the references to the ones you were sure about hadn't been mentioned - just the one clue and pattern (plus answer for 19a) would have been enough
