To provide the finishing touch, has money left to (3,2,3)
I believe the answer is:
cap it all
'to provide the finishing touch' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'money left to' is the wordplay.
I cannot really understand how this works, but
'money' could be 'capital' (I've seen this in another clue) and 'capital' is found in the answer.
'left' could be 'l' (common abbreviation) and 'l' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'has' is the link.
Can you help me to learn more?
(Other definitions for cap it all that I've seen before include "Surpass or outdo something" , "Climax" .)
