I believe the answer is:
demesne
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">lord's estate</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for demesne that I've seen before include "Seed men (anag) -- land attached to a property and retained for the owner's personal use" , "Land attached to manor" , "Large landed property" , "Extensive landed property" , "Estate; sound like belittle" .)
