Trunk carried by a motor somewhere (5)
I believe the answer is:
torso
'trunk' is the definition.
(both can mean a person's chest)
'carried by a motor somewhere' is the wordplay.
'carried by' says the answer is hidden in the clue.
'TORSO' can be found hidden inside 'motor somewhere'.
(Other definitions for torso that I've seen before include "Roots (anag)" , "Body's trunk" , "Chest" , "Limbless statue" , "Body's core" .)
