Time, approximately, for delivery of trunk (5)
I believe the answer is:
torso
'trunk' is the definition.
(both can mean a person's chest)
'time approximately' is the wordplay.
'time' becomes 't' (abbreviation).
'approximately' becomes 'or so' (synonyms).
't'+'orso'='TORSO'
'for delivery of' is the link.
(Other definitions for torso that I've seen before include "Trunk of human body" , "Poorly-dressed child" , "upper body" , "Body without head, neck and limbs" , "part of body will be found" .)
