Unlimited funds for present (5)
I believe the answer is:
offer
'present' is the definition.
(I've seen this before)
'unlimited funds' is the wordplay.
'unlimited' means to look at the middle letters (remove the limits/outer letters).
'funds' becomes 'coffers' (coffers can mean funds or reserves).
The centre of 'coffers' is 'OFFER'.
'for' acts as a link.
(Other definitions for offer that I've seen before include "Pay increase" , "Suggest" , "Tender - proposal" , "Present to or make a bid" , "hand" .)
