Bear or Berra (4)
I believe the answer is:
yogi
I believe this clue is a double definition.
'bear' is the first definition.
(cartoon character Yogi Bear)
'berra' is the second definition.
(I've seen this in another clue)
(Other definitions for yogi that I've seen before include "Master of a Hindu philosophical system" , "master of posturing?" , "Indian mystic" , "Practitioner of yoga" , "one accustomed to spirits" .)
