Come to a close (3)
I believe the answer is:
end
'come to a close' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for end that I've seen before include "Final part" , "Time to break-up (3,2,4) - See 12" , "Concluding purpose" , "For Chelsea or Villa, it's a" , "Finish; goal" .)
