Extreme state (5)
I believe the answer is:
utter
I believe this clue is a double definition.
'extreme' is the first definition.
(I've seen this before)
'state' is the second definition.
(both can mean to say)
(Other definitions for utter that I've seen before include "Express audibly" , "outright" , "Speak; complete" , "Speak or say" , "Absolutely" .)
