Raise back (4)
I believe the answer is:
rear
I believe this is a double definition.
'raise' is the first definition.
(as in rearing children)
'back' is the second definition.
(something's rear is its back)
(Other definitions for rear that I've seen before include "Bring up - the tail" , "Bottom" , "Of horse, rise up on hind legs" , "Breed or bring up" , "Back; bring up (young)" .)
