Wisely cautious (7)
I believe the answer is:
prudent
'wisely cautious' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for prudent that I've seen before include "Careful and sensible" , "With care/forethought" , "Cautious; discreet" , "Thinking of the future" , "Acting with care for the future" .)
