Nobleman with a squint? (4)
I believe the answer is:
peer
I believe this is a double definition.
'nobleman' is the first definition.
(I know that peer is a type of nobleman)
'a squint?' is the second definition.
(I've seen this in another clue)
'with' acts as a link.
(Other definitions for peer that I've seen before include "Squint" , "Look with difficulty; equal" , "Lord of the realm" , "Social equal" , "Equal; nobleman" .)
