Ways to make money (5)
I believe the answer is:
means
I believe this clue is a double definition.
'ways' is the first definition.
(I've seen this before)
'money' is the second definition.
(thesaurus)
'to make' acts as a link.
(Other definitions for means that I've seen before include "Resources or money to support oneself" , "Available resources" , "Indicates" , "Signifies" , "Averages" .)
