Trunk and tangled roots (5)
I believe the answer is:
torso
'trunk' is the definition.
('torso' can be a synonym of 'trunk')
'tangled roots' is the wordplay.
'tangled' is an anagram indicator.
'roots' with letters rearranged gives 'TORSO'.
'and' acts as a link.
(Other definitions for torso that I've seen before include "part of body will be found" , "Body (excluding head, neck and limbs)" , "Limbless statue" , "unfinished work" , "Body's core" .)
