Finishes up (4)
I believe the answer is:
ends
'finishes up' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ends that I've seen before include "Brings to a close" , "Wanting goals" , "See 8" , "Finishes (could be loose or dead?)" , "Finishes (loose or dead, perhaps?)" .)
