Perfect, say (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')
'say' is the second definition.
(thesaurus)
(Other definitions for utter that I've seen before include "Speak - out-and-out" , "Antique offer for sale" , "Total < state" , "in toto" , "Express in words" .)
