Angry about name attached to a religious painting (7)
I believe the answer is:
madonna
'religious painting' is the definition.
(I've seen this before)
'angry about name attached to a' is the wordplay.
I cannot really understand how this works, but
'angry' could be 'mad' (similar in meaning) and 'mad' is located in the answer.
'about' could be 'on' (as in a book 'on' a certain topic) and 'on' is present in the answer.
'name' could be 'n' (common abbreviation e.g. on forms) and 'n' is present in the answer.
'a' is within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for madonna that I've seen before include "US female singer" , "Virgin Mary - or American showbiz queen" , "American pop singer" , "pop star" , "religious painting" .)
