Visible discernment? (7)
I believe the answer is:
insight
I believe this clue is a double definition.
'visible' is the first definition.
(thesaurus)
'discernment?' is the second definition.
(insight is a kind of discernment)
(Other definitions for insight that I've seen before include "Intuitive understanding" , "Awareness" , "Intuition" , "percipience" , "vision" .)
