Belgian town in European country (5)
I believe the answer is:
spain
'european country' is the definition.
(Spain is an example)
'belgian town in' is the wordplay.
'belgian town' becomes 'spa' (**).
'spa'+'in'='SPAIN'
(Other definitions for spain that I've seen before include "European country" , "Country bordering Andorra" , "It pains one to be out in this country" , "Pains badly to be in the country" , "Take pains to go there" .)
