Raise; hindmost part (4)
I believe the answer is:
rear
I believe this clue is a double definition.
'raise' is the first definition.
(as in rearing children)
'hindmost part' is the second definition.
(I've seen this before)
(Other definitions for rear that I've seen before include "parent" , "what can be brought up, finally" , "Bring up (children)" , "Rump" , "Back; bring up (young)" .)
