Send me around Eastern land (7)
I believe the answer is:
demesne
'land' is the definition.
('demesne' can be a synonym of 'land')
'send me around eastern' is the wordplay.
'around' is an anagram indicator.
'eastern' becomes 'e'.
'send'+'me'='sendme'
'sendme' anagrammed gives 'demesn'.
'demesn'+'e'='DEMESNE'
(Other definitions for demesne that I've seen before include "Landed property used by the owner - needs me (anag)" , "Domain" , "Seed men on landed estate" , "Seed men (anag) -- land attached to a property and retained for the owner's personal use" , "Estate; sound like belittle" .)
