All help greatly appreciated.
Thank you again retrocop for your rapid and helpful response. Would you be good enough to explain marvellous (25 across answer) to me please? I cannot parse it.
I have to admit I have since tried to parse it myself.I have the OUS at the end could be Ordinary American.I can only speculate that there is an English poet called Marvell although I can't find a listing under that name in the Poets section of THE CROSSWORD DICTIONARY.Hope someone can help us both by parsing it.I am 100% positive the answer is correct though.
