Bear looking around nobleman (4)
I believe the answer is:
earl
'nobleman' is the definition.
(member of the nobility)
'bear looking around' is the wordplay.
'around' indicates a hidden word.
'EARL' can be found hidden inside 'bear looking'.
(Other definitions for earl that I've seen before include "Noble title" , "Real (anag) - nobleman" , "One who's been elevated" , "Peer (Br.)" , "Aristocrat ranking between marquis and viscount" .)
