Goat with silky hair (6)
I believe the answer is:
angora
'goat with silky hair' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for angora that I've seen before include "Fabric made from goat-hair from Aragon" , "Breed of rabbit or cat, the former name for the Turkish capital" , "Breed of goat with silky hair" , "Soft yarn from certain goats" , "Long-haired cat, goat, or rabbit" .)
