Being on the money, clergyman underwrites a hundred (8)
I believe the answer is:
accurate
'being on the money' is the definition.
(I've seen this in another clue)
'clergyman underwrites a hundred' is the wordplay.
I cannot really see how this works, but
'clergyman' could be 'curate' (curate is a kind of clergyman) and 'curate' is present in the answer.
'a' is present in the answer.
'hundred' could be 'c' (Roman numeral) and 'c' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for accurate that I've seen before include "Careful, precise" , "Correct in all details" , "Exactly right" , "Spot-on" , "Spot on" .)
