Country health resort, fashionable (5)
I believe the answer is:
spain
'country' is the definition.
(Spain is an example)
'health resort fashionable' is the wordplay.
'health resort' becomes 'spa' (I've seen this before).
'fashionable' becomes 'in' ('in' can be similar in meaning to 'fashionable').
'spa'+'in'='SPAIN'
(Other definitions for spain that I've seen before include "European nation" , "EU country" , "Crazy pains?" , "European country" , "Iberian 4" .)
