Lands in eastern nation (6)
I believe the answer is:
estate
'lands' is the definition.
(I've seen this in another clue)
'eastern nation' is the wordplay.
'eastern' becomes 'e'.
'nation' becomes 'state' (synonyms).
'e'+'state'='ESTATE'
'in' is the link.
(Other definitions for estate that I've seen before include "Place for tea or coffee" , "Property and possessions of the deceased" , "Scheme of new housing" , "Land with buildings" , "My wealth" .)
