Bread or dough (5)
I believe the answer is:
money
This clue is a double definition.
'bread' is the first definition.
(slang term for money)
'dough' is the second definition.
(thesaurus)
'or' is the link.
(Other definitions for money that I've seen before include "Coins, banknotes, etc" , "tin" , "Euro for example" , "It's the root of all evil" , "Lucre" .)
