He lives in torment (4)
I believe the answer is:
hell
'torment' is the definition.
(thesaurus)
'he lives' is the wordplay.
'lives' becomes 'll' (I can't justify this - if you can you should give a lot more credence to this answer).
'he'+'ll'='HELL'
'in' is the link.
Can you help me to learn more?
(Other definitions for hell that I've seen before include "Abode of the forces of evil" , "Hades, the netherworld" , "Beelzebub's home" , "Place of suffering" , "Satan's realm" .)
