Spring in the country (5)
I believe the answer is:
spain
'the country' is the definition.
(Spain is an example)
'spring in' is the wordplay.
'spring' becomes 'spa' (spa can mean a mineral spring).
'spa'+'in'='SPAIN'
(Other definitions for spain that I've seen before include "holiday destination?" , "Take pains to go there" , "European nation" , "Crazy pains?" , "Iberian 4" .)
