Completed deliveries (4)
I believe the answer is:
over
This clue is a double definition.
'completed' is the first definition.
(synonyms)
'deliveries' is the second definition.
(I've seen this before)
(Other definitions for over that I've seen before include "Finished like round of bowling in cricket" , "Completely ended" , "Finished, concluded" , "Unit of test" , "balls > left" .)
