Trunk of body (5)
I believe the answer is:
torso
'trunk of body' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for torso that I've seen before include "Roost on trunk?" , "Body (excluding head, neck and limbs)" , "unfinished work" , "Trunk of human body" , "Trunk; headless, limbless body" .)
