An ape shunning hostile goat (6)
I believe the answer is:
angora
'hostile goat' is the definition.
'Angora' can be an answer for 'goat' (Angora goat is an example). I'm not certain of the 'hostile' bit.
'an ape shunning' is the wordplay.
'ape shunning' becomes 'gora' (I can't explain this - if you can you should believe this answer much more).
'an'+'gora'='ANGORA'
Can you help me to learn more?
(Other definitions for angora that I've seen before include "Fine wool from certain goats" , "Name of goat yielding 10 across" , "Name of goat at 12 Across" , "Breed of goat, cat or rabbit" , "Fur of rabbit - hair of goat" .)
