Say; complete (5)
I believe the answer is:
utter
I believe this clue is a double definition.
'say' is the first definition.
(to utter something is to speak or say it)
'complete' is the second definition.
(I know that complete can be written as utter)
(Other definitions for utter that I've seen before include "Dead" , "Say; total" , "Prize" , "Put into words" , "Absolute - state" .)
