Look equal? (4)
I believe the answer is:
peer
This clue is a double definition.
'look' is the first definition.
(peering is a kind of looking)
'equal?' is the second definition.
('peer' can be a synonym of 'equal')
(Other definitions for peer that I've seen before include "one visiting ladies, say?" , "Equal -- look searchingly" , "Social equal" , "Noble; look with difficulty" , "role in Iolanthe" .)
