Bring down hill (4)
I believe the answer is:
fell
This clue is a double definition.
'bring down' is the first definition.
(thesaurus)
'hill' is the second definition.
(thesaurus)
(Other definitions for fell that I've seen before include "avalanche?" , "Highland moor" , "stretch of moorland" , "Lake District hill" , "'I do not like thee Doctor ....'" .)
