Stays with the body (7)
I believe the answer is:
remains
This clue is a double definition.
'stays' is the first definition.
('remain' can be a synonym of 'stay')
'the body' is the second definition.
(remains is a kind of body)
'with' is the link.
(Other definitions for remains that I've seen before include "surviving old parts" , "Archaeological relics" , "What's left (maybe of a body)" , "Scraps" , "Body after death" .)
