His home is detached naturally (8)
I believe the answer is:
islander
'his home' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'is detached naturally' is the wordplay.
'detached naturally' becomes 'lander' (I can't justify this - if you can you should believe this answer much more).
'is'+'lander'='ISLANDER'
Can you help me to learn more?
(Other definitions for islander that I've seen before include "One from Islay, Man, etc" , "Perhaps Sardinian" , "End rails (anag)" , "Isolated dweller" , "Maybe Corfiot" .)
