Land in country, European nation (6)
I believe the answer is:
estate
'land' is the definition.
(I know that land can be written as estate)
'country european nation' is the wordplay.
'country european' becomes 'e' (abbreviation e.g. EU. I am not sure about the 'country' bit.).
'nation' becomes 'state' (synonyms).
'e'+'state'='ESTATE'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for estate that I've seen before include "Houses - car" , "Scheme of new housing" , "Tea-set (anag.)" , "Property left at death" , "Car; landed property" .)
