An aristocrat? He's no better than you are! (4)
I believe the answer is:
peer
'an aristocrat?' is the definition.
(peer is a kind of aristocrat)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for peer that I've seen before include "Look closely at lord" , "Peep; nobleman" , "Struggle to see; equal" , "Look closely - nobleman" , "Member of the nobility" .)
