The noble look (4)
I believe the answer is:
peer
I believe this is a double definition.
'the noble' is the first definition.
(peers are members of the nobility)
'look' is the second definition.
(to peer at something is to look at it)
(Other definitions for peer that I've seen before include "unelected politician" , "One entitled" , "Equal; nobleman" , "Member of the nobility" , "Look hard at the nobleman" .)
