Signifies the wherewithal (5)
I believe the answer is:
means
I believe this clue is a double definition.
'signifies' is the first definition.
('mean' can be a synonym of 'signify')
'wherewithal' is the second definition.
(I've seen this in another clue)
'the' acts as a link.
(Other definitions for means that I've seen before include "unpopular test" , "Indicates" , "Intends; wealth" , "Available resources" , "Money - is significant" .)
