Agree to raise note with charges added (3,3)
I believe the answer is:
see fit
'charges added' is the definition.
I can't judge whether this defines the answer.
'agree to raise note' is the wordplay.
I cannot quite understand how this works, but
'agree' could be 'fit' (fitting is a kind of agreeing) and 'fit' is present in the answer.
'note' could be 'see' (I've seen this in another clue) and 'see' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'with' is the link.
Can you help me to learn more?
(Other definitions for see fit that I've seen before include "Perceive in good shape, so choose to do?" , "Consider suitable" , "Consider appropriate, decide to do" , "Want" , "Consider to be proper or desirable" .)
