Instructed, taught (8)
I believe the answer is:
educated
I believe this clue is a double definition.
'instructed' is the first definition.
(similar in meaning)
'taught' is the second definition.
(educating is a kind of teaching)
(Other definitions for educated that I've seen before include "Maybe enlightened" , "Clever" , "Instructed, taught" , "Having completed schooling, well informed" , "Civilised" .)
