Ingénue agitated? True (7)
I believe the answer is:
genuine
'true' is the definition.
('genuine' can be similar in meaning to 'true')
'ingenue agitated?' is the wordplay.
'agitated?' indicates anagramming the letters (I've seen 'agitated' mean this).
'ingenue' anagrammed gives 'GENUINE'.
(Other definitions for genuine that I've seen before include "Sincere, honest" , "'Real, unfeigned (7)'" , "Authentic; honest" , "Real, not faked" , "Ingenue - the real McCoy" .)
