Shape of dome obscuring supposedly good view (7)
I believe the answer is:
opinion
'view' is the definition.
(I know that view can be written as opinion)
'shape of dome obscuring supposedly good' is the wordplay.
I cannot really see how this works, but
'of' could be 'o' and 'o' is located in the answer.
'good' could be 'pi' (old-fashioned term for pious) and 'pi' is present 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 opinion that I've seen before include "A view held, what one thinks" , "View, judgement" , "Estimation" , "Conviction - point of view" , "Unproven belief" .)
