Bring up the tail-end (4)
I believe the answer is:
rear
I believe this is a quadruple definition!!
'bring' is the first definition.
(thesaurus)
'up' is the second definition.
(thesaurus)
'the tail' is the third definition.
('rear' can be a synonym of 'tail')
'end' is the fourth definition.
(I've seen this in another clue)
(Other definitions for rear that I've seen before include "Bring up - the tail" , "Jump" , "Raise - back" , "early, long before now" , "The back part of something" .)
