Be taken in by bear (3,2,4)
I believe the answer is:
put up with
'bear' is the definition.
(synonyms)
'be taken in by' is the wordplay.
'be taken in' becomes 'put up' (being put up by someone is being housed by them).
'by' becomes 'with' (I've seen this before).
'putup'+'with'='PUT UP WITH'
(Other definitions for put up with that I've seen before include "Tolerate - endure" , "humour" , "Bear" .)
