Take counsel, being cautious (10)
I believe the answer is:
deliberate
This clue is a double definition.
'take counsel' is the first definition.
(thesaurus)
'cautious' is the second definition.
(thesaurus)
'being' acts as a link.
(Other definitions for deliberate that I've seen before include "Carefully thought out" , "Premeditated" , "Done consciously" , "Consider carefully" , "study" .)
