Good and accurate (4)
I believe the answer is:
nice
This clue is a double definition.
'good' is the first definition.
(similar in meaning)
'accurate' is the second definition.
(thesaurus)
'and' acts as a link.
(Other definitions for nice that I've seen before include "Fastidious" , "Pleasant - exact" , "Pleasant city in south of France" , "Charming" , "good" .)
