Look for lord (4)
I believe the answer is:
peer
This clue is a double definition.
'look' is the first definition.
(to peer at something is to look at it)
'for lord' is the second definition.
(peer is a kind of lord)
(Other definitions for peer that I've seen before include "count, perhaps" , "Look with concentration; noble" , "Equal; nobleman" , "Noble; look intently" , "Look searchingly at lord?" .)
