Home help backed country (5)
I believe the answer is:
india
'country' is the definition.
(I know that India is a country)
'home help backed' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'help' becomes 'aid' (synonyms).
'backed' says the letters should be written backwards.
'aid' written backwards gives 'dia'.
'in'+'dia'='INDIA'
(Other definitions for india that I've seen before include "land in the East" , "Eastern region" , "Commonwealth country, independent in 1947" , "Country of the Ganges" , "Country in South Asia" .)
