Grizzly or Kodiak (4)
I believe the answer is:
bear
I believe this clue is a double definition.
'grizzly' is the first definition.
(I've seen this in another clue)
'kodiak' is the second definition.
(I've seen this in another clue)
(Other definitions for bear that I've seen before include "stomach and > suffer" , "Carry - teddy" , "Huge carnivore" , "Tolerate; animal" , "Carry - tolerate" .)
