Support from the bank (5)
I believe the answer is:
shore
I believe this is a double definition.
'support' is the first definition.
(I've seen this before)
'the bank' is the second definition.
(thesaurus)
'from' is the link.
(Other definitions for shore that I've seen before include "Country" , "Coast" , "Prop; coastline" , "Horse (anag.)" , "Beach; prop (up)" .)
