Sorry if my previous comment seemed brusque/sarky. You should have over all length of answer as it's a crossword? which would help my brain do its trawling ..and do both words start with P or just the first? :)
Ah sorry, I was bamboozled by the little red subtitle re prize crossword, now realise that is a link to previous question. Apparently my pre-senile dementia is worse than I thought.
