Old chap from the country (4)
I believe the answer is:
oman
'country' is the definition.
(I know that Oman is a country)
'old chap' is the wordplay.
'old' becomes 'o' (abbreviation).
'chap' becomes 'man' (chap can mean a man).
'o'+'man'='OMAN'
'from the' is the link.
(Other definitions for oman that I've seen before include "Sultanate on the south-east coast of the Arabian Peninsula" , "Land" , "Sultanate in southwest Asia" , "Muscat's country" , "Arab state" .)
