Put up with Winnie-the-Pooh? (4)
I believe the answer is:
bear
This clue is a double definition.
'put up with' is the first definition.
(synonyms)
'winnie-the-pooh?' is the second definition.
(Winnie-the-Pooh is a fictional bear)
(Other definitions for bear that I've seen before include "Carry, convey" , "Endure; animal" , "Pessimistic investor" , "grizzly, perhaps?" , "Heavy carnivorous quadruped" .)
