Put up with Rupert, perhaps? (4)
I believe the answer is:
bear
This clue is a double definition.
'put up with' is the first definition.
(synonyms)
'rupert perhaps?' is the second definition.
(I know that Rupert Bear is a bear)
(Other definitions for bear that I've seen before include "Exhibit" , "Shoulder - stomach" , "Give birth to - large mammal" , "Tolerate - carnivore" , "someone being ill-mannered" .)
