Horned animal, for short (5)
I believe the answer is:
rhino
'horned animal for short' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rhino that I've seen before include "Beastly type that could charge you" , "Cash" , "African/Asian ungulate" , "The necessary" , "Charging animal" .)
