Toon bear or baseball great Berra (4)
I believe the answer is:
yogi
I believe this is a double definition.
'toon bear' is the first definition.
(I've seen this in another clue)
'baseball great berra' is the second definition.
(I've seen this in another clue)
(Other definitions for yogi that I've seen before include "Someone practising certain Hindu disciplines" , "One practises a Hindu philosophy" , "Hindu philosopher" , "Guru's student" , "-- Bear, cartoon character" .)
