barretter, I don't have the crossword in front of me so I hope I'm thinking of the right one. You want to take R for right out of an unusual word for support, to give a word for runs (as in the verb).
Took us a while to get the 15 letter word, but we've done it now and it explains which letter to use in the clashes. The title "Delightful Punishment" is a crossword clue to the word, not a " charade type" clue.
