Wild goat with curved horns (4)
I believe the answer is:
ibex
'wild goat with curved horns' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ibex that I've seen before include "one used to high living" , "Wild mountain goat" , "Mountain-goat" , "Wild goat with double curved horns" , "Mountain animal" .)
