One carving, with inscription, impressive Madonna and child (10,5)
I believe the answer is:
monumental mason
'one carving with inscription impressive madonna' is the definition.
I know nothing about this answer so I can't tell whether this works.
'and child' is the wordplay.
I cannot really understand how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
'child' could be 'son' (male child) and 'son' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for monumental mason that I've seen before include "worker in stone" , "Maker of tombstones" , "Supplier of tablets" , "One employed at a cemetery, perhaps" , "one with grave responsibilities?" .)
