Country's at home beyond spring (5)
I believe the answer is:
spain
'country's' is the definition.
(Spain is an example)
'home beyond spring' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'beyond' means one lot of letters go next to another.
'spring' becomes 'spa' (I've seen this before).
'in' after 'spa' is 'SPAIN'.
'at' acts as a link.
(Other definitions for spain that I've seen before include "Iberian country" , "European nation" , "country of mostly dry mountains, going by air" , "location of Estoril" , "ditto" .)
