Let me ask one last question. Is 23D a fair clue? QuickSolve shows 150+ possiblities but I don't see one among them that fits?
I do think, and I know that this is considered heresy, that 7D, requiring a specific dictionary (without it being mentioned in the instructions as rare or obscure - as is often the case elsewhere, e.g. Harpers), is not a fair clue. I could make up a better clue for it myself quite easily.
