About — completed (4)
I believe the answer is:
over
This clue is a double definition.
'about' is the first definition.
(both can mean around)
'completed' is the second definition.

(Other definitions for over that I've seen before include "Division of play in cricket" , "Six cricket deliveries" , "Finished-up -left" , "left for another day?" , "Concerning" .)
