After initial cut, give positive response to extra money (5)
I believe the answer is:
raise
'extra money' is the definition.
'after initial cut give positive response' is the wordplay.
'after initial cut' means to remove the first letter.
'give positive response' becomes 'praise'.
'praise' with its initial letter taken away is 'RAISE'.
'to' acts as a link.
(Other definitions for raise that I've seen before include "Move higher" , "Heighten" , "Bring up, rear" , "Contact" , "To promote" .)
