Bring up at the back (4)
I believe the answer is:
rear
I believe this is a triple definition!
'bring' is the first definition.
(thesaurus)
'up' is the second definition.
(thesaurus)
'at the back' is the third definition.
(I've seen this before)
(Other definitions for rear that I've seen before include "Hindmost part" , "Bring up (children)" , "Bring up and care for" , "Stern" , "parent" .)
