It has roots, maybe, but no limbs (5)
I believe the answer is:
torso
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'roots maybe but no limbs' is the wordplay.
'roots' anagrams to 'TORSO'.
Though, I'm unsure how this is indicated.
'has' is the link.
Can you help me to learn more?
(Other definitions for torso that I've seen before include "Body's core" , "unfinished work" , "Roost (anag)" , "part of body will be found" , "Trunk of human body" .)
