Put up with stream (5)
I believe the answer is:
brook
I believe this clue is a double definition.
'put up with' is the first definition.
(synonyms)
'stream' is the second definition.
(I know that brook is a type of stream)
(Other definitions for brook that I've seen before include "running water" , "Bear - small stream" , "Stand for" , "Allow" , "Stream; put up with" .)
