Man of the manor (4)
I believe the answer is:
lord
'man of the manor' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lord that I've seen before include "Dismayed expression; ruler" , "Feudal superior" , "Noble title" , "Master, ruler or titled gent" , "Leader of the 'Six Hundred'" .)
