Bring up tail end (4)
I believe the answer is:
rear
This clue is a quadruple definition!!
'bring' is the first definition.
(thesaurus)
'up' is the second definition.
(thesaurus)
'tail' is the third definition.
('rear' can be a synonym of 'tail')
'end' is the fourth definition.
(thesaurus)
(Other definitions for rear that I've seen before include "Rare at the back" , "Buck" , "Hitchcock film set in one room" , "Rise up at the back" , "what you may bring up" .)
