Tense finish (7)
I believe the answer is:
perfect
I believe this is a double definition.
'tense' is the first definition.
(I know that perfect is a type of tense)
'finish' is the second definition.
(perfect can mean to finish off and make perfect)
(Other definitions for perfect that I've seen before include "Flawless - finish" , "Ideal, without flaw" , "Without blemish" , "Past tense; ideal" , "Getting by scheming" .)
