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 cannot judge whether it can be defined by this definition.
'money left to' is the wordplay.
I cannot quite see how this works, but
'money' could be 'capital' (I've seen this in another clue) and 'capital' is found within the answer.
'left' could be 'l' (common abbreviation) and 'l' is found in the answer.
No letters remain.
This explanation may well be incorrect...
'has' acts as a 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" .)
