Initial payment from bank (7)
I believe the answer is:
deposit
I believe this clue is a double definition.
'initial payment' is the first definition.
(I've seen this before)
'bank' is the second definition.
(I've seen this before)
'from' is the link.
(Other definitions for deposit that I've seen before include "store" , "Part payment in advance to secure goods" , "Sum of money paid into a bank account" , "Money given as security" , "Precipitate" .)
