Trunk roots twisted (5)
I believe the answer is:
torso
'trunk' is the definition.
(both can mean a person's chest)
'roots twisted' is the wordplay.
'twisted' indicates an anagram.
'roots' anagrammed gives 'TORSO'.
(Other definitions for torso that I've seen before include "part of body will be found" , "Trunk of human body" , "Body's trunk" , "Trunk; headless, limbless body" , "unfinished work" .)
