Given cash to help? (4)
I believe the answer is:
paid
'given' is the definition.
('pay' can be a synonym of 'give')
'cash to help?' is the wordplay.
'cash' becomes 'p' (abbreviation for pence).
'to help?' becomes 'aid' ('aid' can be a synonym of 'help').
'p'+'aid'='PAID'
(Other definitions for paid that I've seen before include "Settled the bill" , "Discharged a debt" , "Handed over money" , "Given money (for work)" , "See 12" .)
