Objects and stops ... (4)
I believe the answer is:
ends
This clue is a double definition.
'objects' is the first definition.
(I've seen this in other clues)
'stops' is the second definition.
('end' can be a synonym of 'stop')
'and' is the link.
(Other definitions for ends that I've seen before include "Extremities" , "Borders" , "Objectives, purposes" , "Justifications for means, sometimes?" , "Ceases, closes or dies" .)
