Barbarian joining a chap in the country (7)
I believe the answer is:
hungary
'the country' is the definition.
(Hungary is an example)
'barbarian joining a chap' is the wordplay.
'barbarian' becomes 'hun' (as in Atilla the Hun).
'joining' is a charade indicator (letters next to each other).
'a chap' becomes 'gary' ().
'hun'+'gary'='HUNGARY'
'in' acts as a link.
(Other definitions for hungary that I've seen before include "East European country" , "Country where Magyar is spoken" , "Liszt's land" , "country in Europe" , "vizsla from here?" .)
