Perfect state (5)
I believe the answer is:
utter
I believe this clue is a double definition.
'perfect' is the first definition.
('utter' can be a synonym of 'perfect')
'state' is the second definition.
(thesaurus)
(Other definitions for utter that I've seen before include "Circulate" , "Positive" , "Without a single qualification" , "Speak, articulate" , "Complete madman" .)
