True, accurate (7)
I believe the answer is:
factual
I believe this is a double definition.
'true' is the first definition.
(similar in meaning)
'accurate' is the second definition.
(thesaurus)
(Other definitions for factual that I've seen before include "True to life" , "Based on real events" , "Based on things known to be true" , "Based on reality" , "Relating to reality" .)
