One should tolerate such an animal (4)
I believe the answer is:
have
I believe this clue is a triple definition!
'one should' is the first definition.
(thesaurus)
'tolerate' is the second definition.
(thesaurus)
'such an' is a link.
'animal' is the third definition.
(I know that have is a type of figure)
(Other definitions for have that I've seen before include "Take" , "Enjoy yourself!" , "Possess" .)
