He has a home split round the side (8)
I believe the answer is:
resident
'he has a home' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'split round the side' is the wordplay.
'split' becomes 'rent' (past tense of 'rend' meaning to split).
'round' is an insertion indicator.
'rent' placed around 'side' is 'RESIDENT'.
Can you help me to learn more?
(Other definitions for resident that I've seen before include "Liver" , "Person living in" , "Citizen" , "Occupier" , "settled" .)
