Thanks......but I just don't get the clue for the answer, rill as in stream, yes, lots, tons round rill, it's the 19 of 19 of 19 of 19 part, is this me being thick ?
A small stream and the Roman numeral for one inside an informal word for lots, givingtrillions which could also be the answer to 19a (thousands) multiplied by itself three times.
